  1. Note: Models that have a rank that is plausible (i.e., p value of greater than 0.05) are shown in bold. Rank is equal to the minimum number of source populations required to model the “Left” population group relative to the “Right” population group, minus 1 (thus, Rank 2, which is the only working solution for all sets of three “Left” populations, reflects three admixing populations)
