Summary: | Analyses of the 16 outlier SNPs within protein-coding regions, after filtering for a minor allele frequency threshold = 2%, and pruning for linkage disequilibrium a) principle component analysis b) DAPC of the inferred clustering; c1 = inferred cluster 1, c2 = inferred cluster 2 (left) DAPC of Central (1), Seward Peninsula. (2) and Southwest (3) red fox samples in Alaska (right) c) STRUTURE analysis of K = 2, where individuals are represented by each bar along the x-axis and assignment to clusters is represented by the y-axis and the different colours; CN = central Alaska; SP = Seward Peninsula; SW = Southwest Alaska.
