STRUCTURE results with 47 ASMs in the HGDP. The five horizontal groups show the results from STRUCTURE analyses for the H919 dataset genotyped for the 47 ASMs (ascertained with 4gen pairwise FST) as proof of principle. We explored the estimated proportion of contribution of K ancestral populations (or clusters or subgroups) varying K from two to six. Individuals are represented as vertical bars that are partitioned into segments corresponding to their membership of the clusters indicated by two to six different colours. Each colour reflects the estimated relative contribution of one of the four subgroups to that individual's genome and sum up to 100% (indicated at the Y-axis). Individuals were sorted according to their geographical origins (indicated below each group) after completion of the STRUCTURE analyses.
