Reference I Admixture Analysis K=13

Posted by on March 4, 2011

Continuing with Reference I admixture analysis, here is the results spreadsheet.

You can click on the legend to the right of the bar chart to sort by different ancestral components.

If you can't see the interactive chart above, here's a static image.

C1 South Asian C2 Balochistan/Caucasus
C3 Kalash C4 Southeast Asian
C5 European C6 Mediterranean
C7 Papuan C8 Northeast Asian
C9 Siberian C10 Southwest Asian
C11 East African Bantus C12 West African
C13 East African

The new ancestral component at K=13 is C6. I am calling it Mediterranean because it's maximum among Mozabites (63%) and Sardinians (61%) but it is significant all over the Mediterranean.

Northern European groups lose some of their Pakistani/Caucasian component that they had in K=12 and gain in the K=13 European component. Now C5 can probably be called northern European. Most of the new Mediterranean component comes from the K=12 Southwest Asian.

PS. This was run using Admixture version 1.04 so I can make an apples-to-apples comparison with the previous runs.
