Fig. 1From: Highly differentiated loci resolve phylogenetic relationships in the Bean Goose complexa Principal component analysis based on 11,505,116 SNPs discriminates between all goose taxa in this study. Violin plots for different species pairs show that genetic differentiation is concentrated in a few genomic islands: b A. fabalis and A. serrirostris, c A. fabalis and A. brachyrhynchus, and d A. serrirostris and A. brachyrhynchusBack to article page
