Accuracy of SupportMix for three populations. Accuracy of SupportMix ancestry assignments for in silico generated admixed populations. (A) Three way simulated admixture between Yoruba-French-other (green) and Yoruba-Bedouin-other (red) where "other”" is one of the remaining 29 HGDP populations with at least 10 sampled individuals. For each population the accuracy is plotted versus the lowest pairwise F
for the three ancestral populations. (B) Effects of different degrees of admixture proportions in two-way admixture, where αrepresents fraction of ancestry originating from the first population.
