| Description | English: Population structure of Horn of Africa (HOA: Ethiopia, Eritrea, Djibouti, and Somalia) populations in a broad context. ADMIXTURE analysis of 2,194 individuals from 81 populations for 16,420 SNPs reveals both well-established and novel ancestry components in HOA populations. We used a cross-validation procedure to estimate the best value for the parameter for the number of assigned ancestral populations (K) and found that values from 9 to 14 had the lowest and similar cross-validation errors. (A) The differences in inferred ancestry from K = 9–14 are most pronounced in the HOA for K = 10–12, where two ancestry components that are largely restricted to the HOA appear (the dark purple and dark green components). (B) Surface interpolation of the geographic distribution of eight inferred ancestry components that are relatively unchanging and common to the ADMIXTURE results from K = 10–12. |
