Global Admixture Analysis at K=6

December 31, 2013

This new study has one of the biggest global admixture analyses ever done (185 populations at 293,832 SNPs), but it's a little hard to view so I made a more user friendly version of one of the runs. I chose K=6 because it shows clearly the divisions and admixture between the six main racial groups: Capoid (red), Negroid (orange), Caucasoid (blue), Americoid (green), Mongoloid (yellow) and Australoid (purple). Click the image below to enlarge it and scroll down for examples of the racial types.

K=2 separates African from non-African populations.

K=3 reveals a West Eurasian ancestry component [Blue].

K=4 breaks the African component into an African hunter-gatherer ancestry maximized in Bushmen such as the Ju_hoan_North [Red] and an African farmer component maximized in the Yoruba [Orange].

K=5 breaks the ENA [eastern non-African] component down into one maximized in the Karitiana from the Americas [Green] and one maximized in the Ami from Taiwan [Yellow].

K=6 reveals a south Eurasian component maximized in Papuans [Purple], which is also represented in South Asians.
