Fig. 2 Genetic structure of the three species. Genetic structure of the three species. (A) PCA based on SNPs remaining after a 5% minimum allele frequency (MAF) cutoff. (B) Ancestry proportions of each sample estimated by admixture for K = 4 genetic groups. (C) Geographic distribution of ancestry proportions of wild population samples obtained from the same analysis.
