    Here the long-awaited results. Pretty much as expected, with no major surprises. About 2/3rds Black, 1/4 White, 1/12th Asian. The only unexpected things are in my Asian ancestry. Apparently, contrary to what I have been told, I have no South Asian ancestry. Also, of my East Asian ancestry, half appears to be Southeast Asian, rather...
  • Do they always clump British and Irish together? Can they separate that? My folks are from the West Coast of Ireland. I would be about 99.99 percent “British and Irish.” Duh.

    He didn't need the test. He looks and knows he's black. He might have thought the results would be all white. Wishful thinking and a waste of money.

    OTOH, I hear 23&Me likes to report POC heritage when there is none just to mess with people…

  • Notwithstanding small allowances for possible mixed-race pairings in your ancestry prior to roughly the Napoleonic era, and for consanguinity, the most parsimonious explanation would seem to be that of your 128 great-great-great-great-great grandparents, visibly 88 were African black, 30 NW European, 5 SE Asian and 5 Chinese.

  • Just a tidbit to add. My daughter sent saliva samples to both 23&me and Ancestry.com. The results, surprisingly, at least to me, where within .7% of each other.

    In addition, 23&me correctly suggested/identified many relatives out to third cousins.

  • My test came back showing 99.7% Scotch/Irish . My family has been in America since the mid 1800′s and we were told by my Grandmothers when questioning them about our ethnic heritage that we were German and American Indian . We grew up eating scrumptious German cooking . We were also warned when inquiring about our ancestors to beware because we might find out some things we did not want to know . I am not really sure I trust the modern technologies but I do see the application in the end times scenario ie: Revelations 9

    Hmm ... I thought you pretty much have to get half from each parent, and that it is the grandparents' genomes that can--and do--vary considerably.

    I mean, you get one half of each pair of 23 chromosomes from each parent, so each parent ought always to be 50% of your genome. But since your parents do not necessarily give you 50% of each of their parents' genome--indeed, since 23 is not evenly divisible by 4, they cannot give you 50% of each of their parents' genomes--you can end up with wildly disproportionate share any of your grandparents' genomes.

    Perhaps unconscious awareness of this has something to do with why grandparents can sometimes take wildly disproportionate interests in different grandchildren.

    Yup, you’re 50% related to each parent, but not 25% related to each grandparent (and not 12.5% related to each great grandparent and so on). Just the same, you’re not 50% related to each sibling.

    Interesting, thank you.

    Realizing, of course, that her grandfather easily could have been much less than half Kalmyk or much more than half. As you probably know, we don’t necessarily inherit such predictable percentages of genes “proportionately” from each race or ethnicity.

    For example, my Mom’s genetic tests reported that she is more than 10% “Middle Eastern” (Arab / Sephardic Jew) and several percent Ashkenazi (aka “european Jewish”). But my tests showed 0-1% Middle Eastern and only 1% Ashkenazi Jewish. I apparently inherited a “disproportionately” high share of her Italian genes and almost none of her non-Italian genes.

    My wife is 1/8 Kalmyk, and the Asian features are obvious (all non-Asians ancestors have been blonde blue-eyed ethnic Poles or ethnic Russians, she has dark eyes and thick straight black "Asian" hair like her 1/4 Kalmyk father and his 1/2 Kalmyk farther), yet 23andme has her as 99.8% European, .2% Mongolian. 23andme probably considers Kalmyks and other obscure Eurasian peoples as Eastern European.

    Interesting, thank you.

But since your parents do not necessarily give you 50% of each of their parents' genome--indeed, since 23 is not evenly divisible by 4, they cannot give you 50% of each of their parents' genomes--you can end up with wildly disproportionate share any of your grandparents' genomes.

    Perhaps unconscious awareness of this has something to do with why grandparents can sometimes take wildly disproportionate interests in different grandchildren.

    The only anomaly I found in my 23&me results was that I was 25% British/Irish (my Dutch and Norwegian ancestors would be surprised). The only thing I could figure was that I had some of my British/Irish wife's spit in my mouth when I took the sample.

    Um, no, dude, the explanation is simply that you’re British and Irish.

    From genetic tests, I was likewise surprised that this I likely have a little bit of British genes (5%) and 10% Scandinavian.

    I think 23andme is confused by DICh (Dagestan/Ingushetia/Chechnya) and classifies them as a strange Balkan/Middle Eastern/Broad Southern European melange.

    For instance, me (I'm 1/4 Lak, that's Dagestan).

    Which OTOH is pretty strange, since contrary to my expectations, I recall Razib Khan telling me in a conversation that there is a lot of population genetics data from North Caucasians.

    My wife is 1/8 Kalmyk, and the Asian features are obvious (all non-Asians ancestors have been blonde blue-eyed ethnic Poles or ethnic Russians, she has dark eyes and thick straight black “Asian” hair like her 1/4 Kalmyk father and his 1/2 Kalmyk farther), yet 23andme has her as 99.8% European, .2% Mongolian. 23andme probably considers Kalmyks and other obscure Eurasian peoples as Eastern European.

    Interesting, thank you.

    Realizing, of course, that her grandfather easily could have been much less than half Kalmyk or much more than half. As you probably know, we don’t necessarily inherit such predictable percentages of genes “proportionately” from each race or ethnicity.

    For example, my Mom’s genetic tests reported that she is more than 10% “Middle Eastern” (Arab / Sephardic Jew) and several percent Ashkenazi (aka “european Jewish”). But my tests showed 0-1% Middle Eastern and only 1% Ashkenazi Jewish. I apparently inherited a “disproportionately” high share of her Italian genes and almost none of her non-Italian genes.

    That makes sense. I see that they give much wider predictions of relationship now than in the past.

    However, I still have people on 23andme (white Americans with all of their ancestry from places like The Netherlands and Northern Ireland) with fewer than 5 relative matches sharing more than 0.4% total on only 1 matching segment. This is what they now classify as 3rd-6th cousins.

    It doesn't seem to me that their number of genotypes has doubled in the last 5 years, because I have not seen a doubling of the number of '3rd cousin' relationships in the family finder (other than family that I submitted myself.) And I manage accounts for about 20 unrelated people as well.

    As for high quality sequencing and phenotypes, the smartest thing to do would be to specifically subsidize full sequencing for families where many individuals agree to give lots of phenotype data.

    I could easily convince my parents, my siblings, and my aunts and uncles to provide any kind of phenotype data asked of them. Probably even medical records. And I would do it if we were given the full data set at the end.

    I think this would be true for several thousand families at least, and especially families with lots of health problems, and families without any health problems.

  • Not only is 23andme weaker at differentiating among North/South Chinese and other Asians, but also the diverse groups in South Asia. As a South Asian customer for 23andme, I learnt nothing from their ancestry composition percentages which had me as almost 99% South Asian, with minute Middle Eastern, East Asian and European percentages which may well be noise. This gives me no information that I already do not know. So I used the raw data from 23andme on other open calculators from GEDMatch, DNALand and the others, and voila much more information with very ancient ancestry from South India, Central Asia, Caucasus, Anatolia, Steppe, Siberia, Baltics and NorthEast Europe/Volga. Now this is all very distant ancestry (may well be thousands of BC) I understand but still much more useful information. It would be great of 23andme could have differentiation on modern ethnic groups from South Asia, since very distant past data also does not provide extra information. Hopefully this will happen soon.

  • Interesting. The fact is that with any of these companies their database is only representative of the people who take the test. 23andMe made a concerted effort about 10 years ago to get more African Americans in their database and for a short period offered the test for free. That’s how I was able to test. There are many, often remote, areas where very few, if any, people get tested.

    There are other factors to consider also. Some Native tribes refuse to be tested for cultural reasons. As an African American, my biggest pet peeve is that these tests only reveal areas where people ARE CURRENTLY LIVING, who share your dna. It doesn’t really help me much to know that, for example, I match someone who is currently living in Liberia. My ancestors were in this country prior to Liberia being formed. That relative(s) in Liberia now may well be someone descended from an enslaved African American who decided to go to Liberia.

    Dunno. The studies that I’ve seen indicate that cuckoldry is pretty rare:

    This survey of published estimates of nonpaternity suggests that for men with high paternity confidence, nonpaternity rates are typically 1.7% (if we exclude studies of unknown methodology) to 3.3% (if we include such studies). These figures are substantially lower than the “typical” nonpaternity rate of 10% or higher cited by many researchers, often without substantiation…or the median worldwide nonpaternity rate of 9% reported by Baker and Bellis…

    Men who have low paternity confidence and have chosen to challenge their paternity through laboratory testing are much less likely than men with high paternity confidence to be the fathers of their putative children. Although these men presumably have lower paternity confidence than men who do not seek paternity tests, this group is heterogeneous; some men may be virtually certain that the putative child is not theirs, while others may simply have sufficient doubts to warrant testing. Most of these men are in fact the fathers of their putative genetic children; only 29.8% could be excluded as biological fathers of the children in question.

They refer to ‘whites’ as “Europeans” and themselves as “Chinese”. I saw this usage somewhere else recently, where Chinese were referred to as, or included among, “people of colour”, and it really confused me.

    Let me introduce you to Steve Sailer, another writer on Unz who can explain in often hilarious detail the whole "people of color" thing.

    I remembered where I saw it – it was Constance Wu, the Taiwanese American actress, complaining about Matt Damon being cast in a leading role in a block-buster Chinese-American production about the Great Wall (a necessary device to make the film appeal to American audiences; otherwise it was likely to be a financial disaster at the American box office), wherein she referred to herself as a “person of colour”.

    I don’t recall her complaining about the Greater China production of Mulan (not the Disney cartoon, the excellent Chinese block-buster film starring Zhao Wei) having a solitary European guy cast in a less prominent but pivotal role. Maybe she doesn’t watch Chinese films. (By Greater China, I’m referring to a collaboration on that film between Mainland China, Taiwan and Hong Kong – not something you read much about, but it happens.)

    Hong herself says in the article she took the test because she has some physical and mental traits that are untypical of Koreans.

    If you check photos of her on the Internet, she doesn’t look to have any stand-out atypical physical traits. She says something at the beginning about her atypical hair texture – well, not so you’d notice, particularly, but hair texture is not a universal constant among East Asians, it does vary somewhat. She doesn’t look to me to be outside the normal range of variation.

    Genetic evidence rather strongly confirms historical, archaeological and linguistic evidence that suggests that the Japanese predominantly descend from two source populations, an initially male dominated Yaoyi superstrate population within the last couple thousand years, and a Jomon substrate popuulation, with a significant but much smaller female dominated contribution of migrants from China over many centuries at a slow and steady rate.

    The Yaoyi arrived in Japan via Korea (probably closer to 2900 years ago although admixture datas between the populations vary across Japan by centuries due to the long process of conquest of the island chain) so it makes sense that there is deep genetic affinity between Korean and Japanese genetics with a Korean source admixed with a Jomon component that is specifically Japanese and a smattering of other minor contributions.

    Early Japanese derives heavily from the Yaoyi language with significant loan word borrowing from Chinese that accumulates, but has virtually zero Jomon contribution. But, which historical Korean or Northeast Asian language it derives from is controversial. The Yaoyi brought cavalry in warfare and rice farming to what was mostly a fairly advanced for hunter-gatherer sedentary, pottery using, fishing based culture of Jomon (probably closely related in genetics and language to the Relict Ainu population, although certainly speaking a different dialect of the Ainu language family and maybe whole different language(s) within the family).

    The real notable thing about the Yaoyi-Jomon admixture story is the stunning staying power of the Jomon in the mix (autosomally, 54.3∼62.3% in Ryukyuans and 23.1∼39.5% in mainland Japanese, respectively, according to a 2012 study), particularly male Jomon ancestry (with something on the order of 35-45% of Y-DNA in Japan having Jomon ancestry and about a third of Japanese mtDNA being distinctively Japanese Jomon in origin) despite a near complete lack of Jomon contributions to the Japanese language and a rather minimal cultural contribution from the Jomon substrate generally. Most places that have had a male dominated superstrate population haver much lower percentages of substrate Y-DNA than Japan. The possibility that there is more male than female source Jomon ancestry is also remarkable.

    Some small knitpicks:

    Rice farming, yes. Cavalry questionable. The later Yamato conquerors had considerable difficulty in dealing with the more mobile Ainu with their facility with cavalry hit-and-run tactics. I would be more comfortable with the idea that the Yayoi brought a more organized (“continental”) form of warfare to Insular Japan.

    At one point, the Yamato supposedly fielded “Chinese-like” armies with tight infantry formations. Some scholars variously posit that their experiences with the horse-riding Ainu guerillas or the defeat of their expeditionary force on the Korean peninsua (in support of their Baekche allies) by cavalry-heavy Korean armies led them to transition away from infantry-based armies to the more mobile horse-archer-based armies (which in turn became more lancer-based during the civil wars).

    In other words, the cavalry emphasis happened long after the Yayoi arrival, and the idea of the conquest of the Insular Japan by horse-rising invaders from the continent is nowadays either discredited or disputed vehemently.

    A lot of western travelers have impression of northern Chinese as very nationalistic people. Yes, they are right about that.

Not sure how this happens. I bet it is more to do with survive in harsh cold climate without any one else mercy. Also historically, it was always for northerners conquering southerners in both Asia and European histories.

    If you wonder how crazy Korean people are proud of themselves over other people, well, that is how northerners in general are, not just Korean. Do you wonder why North Korea is so confrontational toward USA? All Asian northerners (Mongolian, Manchurian, Northern Han, also Korean) are proud of ourselves no matter how miserable life is.

    Bottom-line, northern people (both Asian and European) are just proud of themselves in their DNA which do not depend on others approval. Bad commentaries from others are meaningless to them. They are highly competitive people. Northern people are fighters who never accept loss. Lost one battle is not reason to surrender your soul. You always seek the chance to win next time. Olympic games reflect such competitive attitude also for people of north origin.

    Southern Chinese on the other hand seems always displaying pessimistic attitude toward themselves. Southeast Asians are even worse. Pureblood of southeast Asian seems to be a shame for them so that every body claimed some kind of Chinese ancestry. That is really pathetic.

    I have access to about 40 Korean data sets at 23andme alone and none of them had a Korean percentage greater than 65. 99 percent is definitely an "East Asian and broadly East Asian" percentage. Hong most likely does not have a recent Japanese or Chinese ancestry.
    It is just the algorithm that 23andme uses.

    P.S. I made a correction to my misinterpreting the 23andme data, but if they utilized all 76 Korean samples mine is the most likely explanation for the discrepancy.

    If they have a lot of say Chinese samples and only 1 Korean sample, and they get a sample that appears halfway between, it makes sense to classify it with the Chinese. This is because whatever dimensional space you are using to determine distance (say, by K nearest neighbor pattern recognition) you are likely to be missing some relevant dimensions. Effectively what’s going on in those dimensions is “luck” as far as you’re concerned, or random chance. But the role of luck is greater if you are comparing two single samples (your sample, and your 1 known Korean in your database) you know very little about that region of space. On some missing dimension the distance might be very great. But the connection to the Chinese data is more data-driven and less speculative.

    This is the same principle La Griffe du Lion used to show that other things being equal, you should hire (or admit to school) from the high IQ group even if tested IQ’s are equal between two candidates. The one from the low IQ group more likely got lucky on test day.

    I tripped over "people of colour" in the title. I live among a population that is 93.6% Chinese, and they do not see themselves as "people of colour". They refer to 'whites' as "Europeans" and themselves as "Chinese". I saw this usage somewhere else recently, where Chinese were referred to as, or included among, "people of colour", and it really confused me. I guess Chinese in America might see themselves included among "people of colour", although I am somewhat skeptical. Chinese in China surely do not, although they may colloquially refer to themselves as "yellow" rather than "white". But they definitely do not group themselves into some conglomerate group which includes South Asians and Africans. They also clearly differentiate between South Asians and sub-Saharan Africans also. Lumping them all into one group has no utility. Perhaps in America it might, although I have difficulty in discerning what useful purpose it would serve.

    I nearly stopped reading at "possible epigenetic explanation for my Jewish conversion", which I saw as a red flag that the writer was not very informed or rational. But I did persevere, and I have to say that I think she has not written a fair and balanced article. And I have no special reason to defend 23andMe, although I am one of their clients.

    I do not know why 23andMe do not differentiate between northern and southern Chinese in their ancestry reports. My half-Chinese daughter would have appreciated having that information. However, from what I have seen of Chinese in PCA plots, there is more of a cline from north to south, rather than two distinct clusters. The spread of data points is not that great anyway, certainly not on a global scale. And some of the "ethnic minorities" in China who can be strongly differentiated in real life on the basis of culture fall on the same PCA splatter of data points, which doesn't assist differentiation at all. So perhaps the problem is where to set the dividing line between who is considered northern and who is considered southern. This problem exists in the real world also - Chinese people argue over where northern China stops and where southern China starts. Most people seem to generally agree that it happens somewhere around Shanghai, but there is no clear general agreement about exactly where. And Shanghainese themselves don't seem to be regarded as one thing or the other, but rather just 'different' - there, the differentiation is made on the basis of language grouping, which is taken as a proxy for ancient differentiation.

    Razib, do you happen to know why 23andMe do not differentiate Chinese? Am I anywhere near close to guessing why, or is it lack of interest on the part of the people themselves, who know where their 'ancestral villages' are and which Chinese dialects/languages they speak, so a simple north-south dichotomy is just not of interest or use to them, when they already have much more fine grained information about their point of origin in the motherland? I guess I could write and ask them, but it's not such a big deal that I had previously thought of doing that.

    And it might not be of much use in my daughter's case anyway - she plots with Uygurs and Hazara, which makes absolute sense. Sorry for overly long comment.

    This most patriotic guy had nerve to perform this patriotic/anti-American piece of music right there in front of US president in White House in USA. He is full of national pride.

    Lang Lang 郎朗 was born in Northern China (Shenyang, Liaoning, China). His father Lang Guoren is a descendant of the Manchu Niohuru family, which brought forth a long line of Qing Empresses

    Yes he is a fellow northerner, a Manchurian, proud of his nation. Not coincidence. You see more this type of people in north.

    All Asian northerners (Mongolian, Manchurian, Northern Han, also Korean) are proud of ourselves no matter how miserable life is.

    Bottom-line, northern people (both Asian and European) are just proud of themselves in their DNA which do not depend on others approval. Bad commentaries from others are meaningless to them. They are highly competitive people. Northern people are fighters who never accept loss. Lost one battle is not reason to surrender your soul.

    Is that why Korea was a long-time tributary state of China and then occupied by Japan for decades? Because they never accepted a loss due to this “Northern spirit”?

    Southern Chinese on the other hand seems always displaying pessimistic attitude toward themselves. Southeast Asians are even worse. Pureblood of southeast Asian seems to be a shame for them so that every body claimed some kind of Chinese ancestry. That is really pathetic.

    As Mr. Khan already and pithily retorted, the only Asians to defeat Western power consistently in the modern era have been the Vietnamese. Dien Bien Phu ’54 and Saigon ’75 ring a bell? They seem to have taught the Chinese invaders a lesson or two, for that matter, around ’79. Some “pathetic” people.

    "Ooops, someone’s grandpa or grandma mated with a communist Chinese invader or a Japanese colonial overlord!"

    Grandpa? Explain how that'd work?

    I think Razib is wrong. I've seen a fair number, and no Korean sample I'm aware of on 23andMe gets anything close to a "99% Korean" output -- there's nothing atypical about Hong's case. (I bet 99% was just the overall East Asian score.)

    ALL of them, just way too universally to be reasonably explained through recent mixture, get parsed as low majority "Korean" (usually in the range of 50-60%) + "Japanese" somewhere in the region of 20% + remainder Chinese, with low amounts of other stuff. And as I think was mentioned you see peculiar things like the whole X chromosome getting painted as "Japanese". Just smells wonky.

    Grandpa? Explain how that’d work?

    I know a Korean-American whose great-grandmother was Japanese. His great-grandfather was apparently quite successful during the Japanese occupation of Korea (which likely means that he was a collaborator) and married a Japanese woman.

    This was obscured by the family in the post-colonial era.* He only found out, because he ended up marrying a Japanese-American woman, and his mother finally confessed to him before the wedding that she was 1/4th Japanese (and he 1/8th Japanese) and that his children would be slightly more Japanese than Korean (9/16th).

    Real life melodrama, like something out of some K-drama program.

    Just as many Frenchmen claimed to have been Maquisards during the German occupation when in reality they collaborated to varying degrees, post-colonial Koreans often claim that their families valiantly resisted the Japanese occupation when most probably collaborated and even adopted Japanese names (e.g. the South Korean military dictator – and the father of its industrialization – President Park Chung-Hee was at one time an ethnic Korean Japanese Imperial Army officer Takagi Masao who informed on Korean guerillas).

    I have access to about 40 Korean data sets at 23andme alone and none of them had a Korean percentage greater than 65. 99 percent is definitely an "East Asian and broadly East Asian" percentage. Hong most likely does not have a recent Japanese or Chinese ancestry.
    It is just the algorithm that 23andme uses.

    P.S. I made a correction to my misinterpreting the 23andme data, but if they utilized all 76 Korean samples mine is the most likely explanation for the discrepancy.

    My wife and her sister have four known North Korean grandparents with known sub-localization within North Korea, at least two known great-grandparents are also of North Korean ancestry. Family genealogy beyond that was lost in flight from North Korea to South Korea. But there is no known non-North Korean ancestry in the family, and if there was any the most likely source would be Siberia/Manchuria which is consistent with their mtDNA (something found in far more unrelated Korean-Americans on 23andMe than mtDNA studies of Korea and random chance would suggest). Any phenotypic deviation from the North Korean mean in them and their parents also tends to be more in the Siberian direction and less in the Japanese direction.

    But, 23andMe classifies them as about 25% Japanese, and my son is actually classified as more Japanese than Korean (more than 25%) (I’m a European mutt).

    Admittedly, cryptic Japanese ancestry in their great-grandparents generation is possible, there are cultural reasons why Japanese ancestry in an ancestor might not be acknowledged, and that generation would have lived at a time of Japanese dominance of Korean affairs.

    But, I agree with Hector, that in light of the larger sample of purportedly pure-blooded Korean results at 23andMe, I think it is at least as plausible that the Korean samples are misclassifying some ancestry as Chinese or Japanese, when a label like “broadly East Asian” would be more appropriate, or in the case of the Japanese, perhaps because a probably regional rural Korean population that contributed significantly to the Yaoyi migrations to Japan (possibly now found in much greater proportions in North Korea) is undersampled in the 23andMe reference group (which probably heavily oversamples affluent Seoul South Koreans), or in the case of Chinese, due to admixture into Korea both gradual and punctuated over the last 1000 years.

    But in the age of SJW clickbait, can you say you're surprised? 23andme's biggest problem is that their new website is awful.

    "First, they don’t have that many Asian customers. Second, their Asian customers might actually get a bit irritated!"

    Could you explain this more? Do you think Asians set greater store by their ancestry results? The author of this article definitely seems miffed by hers.

    Incidentally, would you be willing to look over individual/family results (if paid), or do you know someone who would? I have some questions about my family's results.

    Gawd yes, 23andme’s new website is awful! I went from visiting it daily to visiting only when a new match sends me an invitation to share genomes. Even then, the experience is very disappointing. I did get an invitation from a cool new relative last week, a mixed race Bermudan woman who lives in the UK. She is descended from a Danish immigrant who married a mixed African, Indian and British woman. I believe, due to research, that we are related by the British side. Although, any Danish DNA I have is by way of my British ancestry. Her family is deeply involved in the Bermuda Police Department and they have been noted physicians, as well.

    GEDmatch is so much more fun than 23andme that I continue to support them with my hard earned dollars. In contrast, I only paid 23andme once, with my original payment. I would never give them any more money until they revamp their “new” website.

    I don’t understand why a Manchu nationalist would be pro-Han Chinese. A typical Manchu nationalist of the 17th Century probably would have considered Chinese subhuman as they showed no mercy when they massacred 7-80 percent of Han Chinese they initially conquered. It was so brutal that well documented and well researched papers exist in regard to the sharp population reduction(up to 5 ~10 fold) in northern China.

    Chinese called to drive out “foreign devils” when they rose against their Manchu overlords in the late 19th Century. Manchu were your overlords and more importantly foreigners, not your fellow Chinese up until 1945 or so when you desperately needed their lands.

    漢城 etc derives from 漢水 – Han River. It was probably a phonetic transcription since there is an alternative transcription – 寒水 (Cold River) which has the same phonetic value in Korean. Actually the wiki link the Chinese jingoist provided specifically says so. LOL.

    This region was a gateway to China as ports like 唐項城 (Tang Neck Port – Gateway to Tang) exist so 漢城 probably won out over other alternative transcriptions.

    Finally, to the best of my knowledge 23andme does not sequence actual segments(unless you call matching primers as sequencing). The cost would be prohibitive otherwise. They type SNPs and make statistical decisions. The link Razib provided specifically states that this method does not work for “closely related populations”. Even though there are sharp distinctions between Chinese and Korean, for global consideration, the two are “closely related”.

    Hello, Razib.

    You gave a rebuttal to why 23andme doesn't have more specificity to East Asians (all non-Europeans really) because you say basically, "they just don't want to." That's okay.

    But what about YOU and Family Tree DNA's pretty awful myOrigins?
    If I'm not mistaken, YOU were behind FTDNA's myOrigins.
    Can't help but notice that you were silent on this issue.

    The previous Population Finder had a decent list of East Asian reference populations. Multiple groups within China.
    http://www.dna-testing-adviser.com/population-finder.html
    It was probably the best test for East Asians at the time.

    The Native American panel on Population Finder was the same as it is on 23andme, Tribecode, and maybe ancestry.com's ancestryDNA (who doesn't list their reference populations, as far as I'm aware of): the Five HGDP groups.

    Also, while West African data was definitely not good (it only had two references: Yoruba and Mandenka) , things were a bit better than they would become with my Origins.....


    For some strange reason, when myOrigins was done.... you or someone at FTDNA or both you and that someone at FTDNA... decided to subtract quite a lot of the Population Finder's non-European reference populations....
    The East Asian references were reduced so badly that there's just a genetic "East Asian" result with no specificity at all.
    https://www.youtube.com/watch?v=0Mt5vWjT8ko

    Three of the five Native American references were taken away which skewed results for people of Native American ancestry.

    "This is probably because myOrigins dropped Maya, Pima and Columbian as reference populations. They were included in Population Finder.

    "Now that they have gotten rid of Pima, Columbian and Maya as reference populations the new and decidedly not improved myOrigins"

    You took also away one of only two West African references which skewed the results people of West African descent as high percentages of "East African."

    Over the last two years, there hasn't been an explanation that one can find online for why this was done.

    Since you are acknowledging how non-Europeans do have it worse on these tests than European, maybe you could also take sometime to address why myOrigins, which you were a part of, was handled as poorly as it was.

    I've been involved in genetic genealogy companies over the past 5 years...aside from Family Tree DNA's myOrigins, not one other company has regressed on their tests. FTDNA was the only company to do this. If you couldn't add any new references, what was the purpose of subtracting them and screwing up peoples' results?

    Would you mind finally addressing this Razib, or are you going to continue to be silent on why such a poor job was done?

    It came across as not just "well we just don't have any new references for non-Europeans," but "non-Europeans can go to hell. We'll improve ethnicity just for Europeans only." Yes, it did seem like FTDNA just had a neglectful attitude for non-Europeans.

    You can't just come up with the excuse of "well, most of the customers are white European," because that's still no excuse to just cut SO MANY of the non-European references, even if it were true that no new non-Europeans were attainable, which is doubtful because 1000 Genomes does have some new African references, for example.

    If you are going to finally address it, please also address why is it that late last year, there were reports that myOrigins would update its ethnicity in the first quarter of 2016.
    The first quarter means the first three months.
    Obviously, it's almost September, way past the first quarter.

    No myOrigins update, and no explanation has been given why there hasn't been.


    I'll be looking forward for an explanation. Please try not to use a cop out like, "well, Family Tree DNA isn't the only company you can do 23andme or ancestryDNA..."
    Again, I'd like to know about you at FTDNA and why myOrigins was handled so badly.

    1) you should post on the open thread.

    2) one answer is i don’t know why myOrigins v2 is late. i stopped working for them this spring due to my various other commitments. when they do release the next version, i will help in any way i can. but they’ll loop me in only on a need to know basis (yeah, it’s late, i don’t know why, the goal was to get to release it in winter).*

Not sure how this happens. I bet it is more to do with survive in harsh cold climate without any one else mercy.

Do you wonder why North Korea is so confrontational toward USA? All Asian northerners (Mongolian, Manchurian, Northern Han, also Korean) are proud of ourselves no matter how miserable life is.

    Bottom-line, northern people (both Asian and European) are just proud of themselves in their DNA which do not depend on others approval. Bad commentaries from others are meaningless to them. They are highly competitive people. Northern people are fighters who never accept loss. Lost one battle is not reason to surrender your soul. You always seek the chance to win next time. Olympic games reflect such competitive attitude also for people of north origin.

    Southern Chinese on the other hand seems always displaying pessimistic attitude toward themselves. Southeast Asians are even worse. Pureblood of southeast Asian seems to be a shame for them so that every body claimed some kind of Chinese ancestry. That is really pathetic.

    I don't understand why a Manchu nationalist would be pro-Han Chinese. A typical Manchu nationalist of the 17th Century probably would have considered Chinese subhuman as they showed no mercy when they massacred 7-80 percent of Han Chinese they initially conquered. It was so brutal that well documented and well researched papers exist in regard to the sharp population reduction(up to 5 ~10 fold) in northern China.

    Chinese called to drive out "foreign devils" when they rose against their Manchu overlords in the late 19th Century. Manchu were your overlords and more importantly foreigners, not your fellow Chinese up until 1945 or so when you desperately needed their lands.

    漢城 etc derives from 漢水 - Han River. It was probably a phonetic transcription since there is an alternative transcription - 寒水 (Cold River) which has the same phonetic value in Korean. Actually the wiki link the Chinese jingoist provided specifically says so. LOL.

    This region was a gateway to China as ports like 唐項城 (Tang Neck Port - Gateway to Tang) exist so 漢城 probably won out over other alternative transcriptions.

    Finally, to the best of my knowledge 23andme does not sequence actual segments(unless you call matching primers as sequencing). The cost would be prohibitive otherwise. They type SNPs and make statistical decisions. The link Razib provided specifically states that this method does not work for "closely related populations". Even though there are sharp distinctions between Chinese and Korean, for global consideration, the two are "closely related".

    Is that why Korea was a long-time tributary state of China and then occupied by Japan for decades? Because they never accepted a loss due to this "Northern spirit"?

    I know a Korean-American whose great-grandmother was Japanese. His great-grandfather was apparently quite successful during the Japanese occupation of Korea (which likely means that he was a collaborator) and married a Japanese woman.

    This was obscured by the family in the post-colonial era.* He only found out, because he ended up marrying a Japanese-American woman, and his mother finally confessed to him before the wedding that she was 1/4th Japanese (and he 1/8th Japanese) and that his children would be slightly more Japanese than Korean (9/16th).

    Real life melodrama, like something out of some K-drama program.

    Just as many Frenchmen claimed to have been Maquisards during the German occupation when in reality they collaborated to varying degrees, post-colonial Koreans often claim that their families valiantly resisted the Japanese occupation when most probably collaborated and even adopted Japanese names (e.g. the South Korean military dictator - and the father of its industrialization - President Park Chung-Hee was at one time an ethnic Korean Japanese Imperial Army officer Takagi Masao who informed on Korean guerillas).

    That’s because Gogureyo was vanquished by the Tang-Silla alliance, and the Tang carried off the surviving elites.

    My wife is 1/8 Kalmyk (she, her father and grandfather show progressively more Asian features), a small Asian ethnic group in Russia, originally from near Mongolia (Kalmyks were allowed to settle in European Russia because they were Muslim-fighters). The 23andme algorithm for some reason has her as being 99.6% European, .3% Mongolian. If they have only 76 Korean samples I suspect they have zero Kalmyk samples and that the Kalmyk ancestry is simply placed under "Eastern European."

  • We probably expect too much from these “DNA” service-companies. In reality using allele frequencies and/or haplotype groups we can provide broad backgrounds of ancestry; what we can not reliably do is date* ancestral “clines” and delineate precise ancestral populations. One reason for this are reference-sets. Virtually all current populations are admixed to some degree, and many of the ancient and medieval populations no longer exist. The DNA companies themselves have helped sell us expectations they can not deliver. If you are an Ashkenazi, 23andMe or FTDNA will tell you, you are an Ashkenazi {which may be as exciting as being told your current shoe size} you will also get to see 1500 close relatives who are most likely unrelated to you in any traceable way. And Ashkenazi is an easy one because it is somewhere between an ethnic-group and an extended family. My biggest complaint with the two above companies is the exploration of their findings is mostly closed. How did they arrive at 7 cM Japanese? 2% Central Asian? etc. These are things you need to explore yourself with your own data, and possibly conclude that all “minority” ancestry is possibly real and yet speculative.

    * Larger data sets can “date” admixture using Alder, GlobeTrotter, TRACTs etc. Many folks regard these admixture-dates with suspicion.

    I would recommend that anyone really interested in their results should immediately download their data set. If they have a parent or children, then encourage them to also have the same type of genome analysis.

    Then there are easy tools online to analyze it further. You can impute missing markers ( which are usually pretty good, I've tested leaving out 10% of the actual data and comparing ). You can phase your data ( much better with a parent of child to compare ). You can upload it to other sites for family finding and ancestry analysis. You can practice writing Python code to compare it to other data sets... lots of things to do.

    I agree that 23andme has a crappy and frustrating web site, but I also understand why it is that way.

    But... if they were really smart, they would give people 100% free DNA tests ( and throw in a free one for a parent or child ) if they honestly filled out all the phenotype data ( and the honesty could be judged by genetics known with high accuracy ).

I’m too lazy to spend more time figuring out in detail what their databases are, but it appears you have spoken with both, and might no more, specifically.
    I’ll also note, and am sure because I was just asked for the details over again, that 23andMe, if they are adding anything to their database based on your stated ancestry, asks where your grandparents were born, and for most Euro-Ancenstry Americans, that is in the US, and so irrelevant to ancestral populations. It’s unclear to me whether they’re using responses to this self report question to add to the 23andMe set (more substantial than Public set), or what.

  • In addition to the long DNA segments that inferred recent Chinese
    ancestry, the surname itself also inferred ancient Chinese ancestry,
    i.e.

    https://en.wikipedia.org/wiki/Hong_(Korean_surname)

    There are about four main Korean Hong clans, the biggest of which
    is the Namyang clan of which about 80% have distant Tang Chinese
    ancestry. Historically anytime ancient Chinese imperial court
    officials had ‘serious disagreement’ with the emperors they tended
    to self-excile to places like Goryeo/Goguryeo. The common Chinese
    surname Ko is also linked to the Goryeo dynasty. The ancient capital
    of Goguryeo is currently a UNESCO heritage site in China.

    https://en.wikipedia.org/wiki/Capital_Cities_and_Tombs_of_the_Ancient_Koguryo_Kingdom

    There were also many Tang elites migrated to Fujian and they also shared
    many common word pronounciations and meaning with Korean, e.g. gangnam
    is pronounced exactly the same and has the exact cultural meaning.

    And during the Korean war there were two million Chinese soldiers
    in Korea …

    "The ancient capital of Goguryeo is currently a UNESCO heritage site in China."

    So how long has it been inhabited by Chinese? Jilin is Manchuria and opened up for mass Han settlement very late, in the latter Qing.

    That's because Gogureyo was vanquished by the Tang-Silla alliance, and the Tang carried off the surviving elites. Mr. Khan and I had a discussion about the impact of the Battle of Talas at some point, and I should note that the Tang commander at Talas was one Gao Xianzhi, the son of a Gogureyo exile: https://en.wikipedia.org/wiki/Gao_Xianzhi

    My wife is 1/8 Kalmyk (she, her father and grandfather show progressively more Asian features), a small Asian ethnic group in Russia, originally from near Mongolia (Kalmyks were allowed to settle in European Russia because they were Muslim-fighters). The 23andme algorithm for some reason has her as being 99.6% European, .3% Mongolian. If they have only 76 Korean samples I suspect they have zero Kalmyk samples and that the Kalmyk ancestry is simply placed under "Eastern European."

  • I take your point about the concentration on NW europe. Yet I wish I had finer detail on the bit of mine that is “21.3 % broadly NW european”. When I look at relatives on the site, almost everyone is american, i.e european emigrants. Do you think as the company gets more actual european customers, anything will change, or will your 10/100 or 100/10000 rule apply?

    Having a Kalmyk great-grandfather doesn't mean you'll necessarily inherit 1/8 of your genome from him.

    It's more like picking 13 cards at random from a deck. On average you'll get 3.25 Spades but in any one sample you might get none.

  • I have access to about 40 Korean data sets at 23andme alone and none of them had a Korean percentage greater than 65. 99 percent is definitely an “East Asian and broadly East Asian” percentage. Hong most likely does not have a recent Japanese or Chinese ancestry.
    It is just the algorithm that 23andme uses.

    P.S. I made a correction to my misinterpreting the 23andme data, but if they utilized all 76 Korean samples mine is the most likely explanation for the discrepancy.

    My wife and her sister have four known North Korean grandparents with known sub-localization within North Korea, at least two known great-grandparents are also of North Korean ancestry. Family genealogy beyond that was lost in flight from North Korea to South Korea. But there is no known non-North Korean ancestry in the family, and if there was any the most likely source would be Siberia/Manchuria which is consistent with their mtDNA (something found in far more unrelated Korean-Americans on 23andMe than mtDNA studies of Korea and random chance would suggest). Any phenotypic deviation from the North Korean mean in them and their parents also tends to be more in the Siberian direction and less in the Japanese direction.

    But, 23andMe classifies them as about 25% Japanese, and my son is actually classified as more Japanese than Korean (more than 25%) (I'm a European mutt).

    Admittedly, cryptic Japanese ancestry in their great-grandparents generation is possible, there are cultural reasons why Japanese ancestry in an ancestor might not be acknowledged, and that generation would have lived at a time of Japanese dominance of Korean affairs.

    But, I agree with Hector, that in light of the larger sample of purportedly pure-blooded Korean results at 23andMe, I think it is at least as plausible that the Korean samples are misclassifying some ancestry as Chinese or Japanese, when a label like "broadly East Asian" would be more appropriate, or in the case of the Japanese, perhaps because a probably regional rural Korean population that contributed significantly to the Yaoyi migrations to Japan (possibly now found in much greater proportions in North Korea) is undersampled in the 23andMe reference group (which probably heavily oversamples affluent Seoul South Koreans), or in the case of Chinese, due to admixture into Korea both gradual and punctuated over the last 1000 years.

    If they have a lot of say Chinese samples and only 1 Korean sample, and they get a sample that appears halfway between, it makes sense to classify it with the Chinese. This is because whatever dimensional space you are using to determine distance (say, by K nearest neighbor pattern recognition) you are likely to be missing some relevant dimensions. Effectively what's going on in those dimensions is "luck" as far as you're concerned, or random chance. But the role of luck is greater if you are comparing two single samples (your sample, and your 1 known Korean in your database) you know very little about that region of space. On some missing dimension the distance might be very great. But the connection to the Chinese data is more data-driven and less speculative.

    This is the same principle La Griffe du Lion used to show that other things being equal, you should hire (or admit to school) from the high IQ group even if tested IQ's are equal between two candidates. The one from the low IQ group more likely got lucky on test day.

    Correction: the numbers inside the ovals are probably the number of populations, not the actual sample size. Actually it explains better why there is a bias in favor of assigning a segment to Chinese or Japanese origin.
    78 for 8 populations means that there were probably 3 Koreans there at most and bias can be substantial.

  • As part of our agreement, I refrained from commenting at Razib’s blog but this is just too much. Razib should read how 23andme’s ancestry report is generated.
    Those who have an account at 23andme can see for themselves.

    https://you.23andme.com/reports/ancestry_composition/details/

    South Asians don’t get much resolution because there is just 1 in the reference panel.
    There are only 8 East Asians that include SE Asians.
    Koreans were only recently added so I strongly suspect there is just 1 against multiple Chinese and Japanese samples. If A Korean has a shared segment with Chinese or Japanese it will be assigned as “Chinese” or “Japanese”. Not only because there are greater numbers(maybe 2-3) of Chinese and Japanese but also because the algorithm favors an “older” classification.
    Most Korean samples I have access to have 10-20 percent of Chinese and 20-30 percent Japanese ancestry whereas Chinese and Japanese have >90 percent of their own. That does not mean Koreans are mixtures of Chinese and Japanese as amateurs like Razib may infer.

    Also the segmental length pictured there is misleading unless one knows how it was developed.
    It is NOT the actual length of a shared segment. There used to be a graph that showed the actual lengths of shared segments but I no longer see it. As the way they presented many Koreans have many whole chromosomes entirely belonging to Japanese and segments about half the size of the whole chromosome belonging to Chinese. These are NOT actual lengths of shared segments.

    Euny Hongs’ 15 percent fictitious Japanese and Chinese ancestry is typical for South Koreans.
    I suspect that her ancestry is more toward Central and Northern Korea and probably Western part. Southeastern Koreans have a strong bias in favor of Japanese and Chinese component is often less than 8 percent for them even on the “speculative”.

    Also this setting is on “speculative”. If you move the knob to “conservative” you get much lower percentages, not only for Japanese and Chinese segments but for Korean segments as well as it is unlikely that one shares too many segments with the sample Korean, the size of 1!! The default setting used be “moderate” but 23andme moved it to “speculative” probably for a commercial concern.

    There used to be a PCA graph that was probably removed now but Koreans and Japanese have no overlap but close enough to nearly touch each other while Chinese, even northern Chinese, are far from all Koreans. This was discussed in some academic papers as well but Chinese occupy intermediate positions between Koreans and SE Asians.

    For myself and my mum it would have been great if there was a breakdown of our non-European components a bit more. We are mixed race and were very surprised when we came out more Asian than we were African. People always said to my mum growing up that they thought she looked Chinese but she dismissed it having been told that we are European and African. Turns out these people were right and my mum is in fact about 1/3 Asian. Our African they attribute almost entirely to West Africa but their samples for East Africa are not great, they only have 119 in total, 29 from 23andme and the rest public, and I’m not sure if they have any Malagasy at all for example. I originally set out with the DNA to find out more about my mother’s side of the family because it is half of her heritage that she knew very little about. The thing that has been the most handy isn’t actually the ethnicity estimates but the genetic matches, they have helped guide my research and broken down so many brick walls so it wasn’t all a complete waste of time. I’ve made contact with 2nd cousins I didn’t know to 4th/5th cousins from all over the world. I was told take the ethnicity estimates with a pinch of salt and back it up with paper research if you can (I know that isn’t always possible where the records are missing). The fact that my mother has 4th and 5th cousins in China and are 100% Asian probably means that her Chinese isn’t “noise” though 1/3 is probably way too much to be “noise”. It’s a topic that has been discussed a lot on various groups with regards to non-European populations.

    they don't use germline.

    Would a PCA work very well for her? Koreans tend to be between Chinese and Japanese in PCA’s featuring them all, and if she has 1/8 of her ancestry from both it could cancel out.


    not just PC 1 and and PC 2. there is surely one that separates north vs. south chinese.

    In my experience the Chinese cline is often incorporated into PC1 or PC2 already, even when there’s something extreme like Ainu included.

    http://www.nature.com/jhg/journal/v60/n10/fig_tab/jhg201579f1.html#figure-title

    But perhaps one of the less significant dimensions can repeat the cline without making Koreans intermediate between China and Japan.
