Additional file 5: Figure S1. of Identification of genomic variants putatively targeted by selection during dog domestication

PCA plot of samples included in this study. PCA of genome-wide polymorphism data from 67 dogs and 7 wolves. The percentage of the total variance explained by the first and second principal component are labeled on the X and Y axis, respectively. PC1 clearly separates dogs from wolves while PC2 primarily separates dogs by geographic origin. (DOCX 144 kb)
