My recollection was that it was more shifted toward sub-Siberian populations, such as Mongolians, who also are suggested to have affinities with Koreans and Japanese. My method was simple, I ran ADMIXTURE in supervised mode with a sample of 10 Han and 10 Japanese I randomly yanked out of the HGDP along with Uygurs, and assorted other groups. I left Uygurs, Chuvash, Turks, and Mongolians &#8220;free&#8221; to be linear combinations of the ancestry of other populations. The marker set was 290,000 (I pruned somewhat from 500,000+), and K = 11 (there were 11 populations which were part of the supervised run).<strong> It looks like the Uygurs have more of an affinity to the Japanese, or at least their East Asian ancestors did<\/strong>.<\/p>\n<p><a href=\"http:\/\/blogs.discovermagazine.com\/gnxp\/files\/2012\/09\/uyg4.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-18270\" title=\"uyg4\" src=\"http:\/\/blogs.discovermagazine.com\/gnxp\/files\/2012\/09\/uyg4.png\" alt=\"\" width=\"600\" height=\"1055\" \/><\/a><\/p>\n<p>Of course, it could be that I sampled an unrepresentative class of 10 Han or Japanese.
