Statistical summary of genetic variation based on principal component analysis of 14,815 common variants, with a PC1 against PC2, and b PC2 against PC3, with colors assigned to individuals with posterior estimated admixture proportions above 95%, where the legend in b is used for both figures. Hybrids with less than 95% admixture proportions are drawn as crosses, and hybrids with more than 50% admixture proportions from a particular species are drawn as colored circles in the respective color with a cross
