@Wang? 這是關于蒙古人在貴州非常有趣。感謝您尋找到這一點。

這篇貴州日報的報道很有意思。不知其它省份是否也有大量從元朝留下的蒙古人？中國的學者好像多數認為蒙古人的祖先是鮮卑的一支，但有些蒙古共和國的學者認為他們的祖先是匈奴的一支。不管從哪來，大概很多鮮卑人和匈奴人都留在了中國北方，與當地的漢族和其他民族同化了。不知是否有出土的古尸能把元朝時蒙古人與鮮卑人和匈奴人分開？

"75.49% Southern Han, 21.59% Mongol Ethnic Group, and 2.87% Shes. "
?I think probably you can look at the recent northern-southern admixed populations in southwest China. there are actually lots of Mongolians in Guizhou, living together with southern natives. for example, the Mongolian people with surname "Yu" in Bijie:http://www.xjass.com/ls/content/2012-11/21/content_254060.htm

that's only a possibility,?make sure not to over-interpret?the data...

75.49% Southern Han, 21.59% Mongol Ethnic Group, and 2.87% Shes.?

@GGal Based on what I've seen, many Northern Han Chinese get significant percentages of Mongolic ancestery at WeGene. So, it is also possible that one or more of her grandparents originally came from Northern China. What are the exact percentages of her ancestry as estimated by WeGene?

@ctlb and @Wang?我很欣賞你的輸入。這是有道理的。我會做對中國的蒙古來說少數民族一些研究。我的女兒是從貴陽。她的一個近親可能是從一個少數群體。這是有用的信息！

ancestry compositions highly depend on the reference populations and how many markers used in the estimation. The 20% “Mongolian ancestry" ?in your daughter would be interpreted as “Mongolian related ancestry”, probably caused by shared alleles with various northern minorities living together with Mongol rather than directly from recent Mongol grandparents. ?

@GGal In addition, 23andMe's definition of Chinese is broad?including not only the Han but probably also varous ethnic groups that speak Mongolic languages and primarily reside in China (e.g., Tu and Dongxiang), but these groups would fall under WeGene's category of Mongolic Ethnic Groups.

@GGal WeGene and 23andMe use different reference populations, so it?is not surprising that their estimations of your daughter's ancestry composition would differ. If I understand it correctly (I have no other tie to WeGene except for being a customer), WeGene's Mongolic Ethnic Groups （蒙古族群）include not only Mongolians but also other ethnic groups that speak Mongolic languages and reside primarily in China. Probably for these reasons, WeGene also attributes a substantial fraction of my DNA (well over 30%) to Mongolic Ethnic Groups even though 23andMe reduced its estimate of my Mongolian DNA from about 12% to 0% after phasing. WeGene's Chief Scientist @wang can probably give you a more definitive answer.
