Fig. 2
The spatial patterns of the average values of intraspecies nucleotide diversity in H. pyrrhocephalus and in H. sp. ‘macula’ (πW; pink); average pairwise nucleotide divergence between the species (πB; blue); and FST (green). (a) Typical genomic regions. (b–e) Candidates of the target genes of divergent selection. The green arrows represent fixed nucleotide differences between species. Green and blue solid lines indicate differentiated regions (DRs) and exons of genes, respectively. The positions of DRs are described on the right side of the green lines
