Figure 1. — Genetic relationships and population structure of the 60 dogs based on all autosomal SNPs. (A) Principal component plot. The first (PC1) and second component (PC2) are shown in the main figure, while the third (PC3) and fourth component (PC4) are shown in the inset. The percentages indicate the proportion of variance explained by each component. (B) Unrooted neighbor-joining tree. The evolutionary distance is measured by the number of net nucleotide substitutions between individuals. (C) Population structures with the number of ancestral clusters K from 2 to 6. Each color represents one ancestral cluster and each vertical bar represents one dog. The length of colored segments represents corresponding ancestry attributions.
