Nucleotide diversity and Tajima’s D calculated for dogs and North American wolves. Across 5 Mb surrounding the K locus core, nucleotide diversity (A) and Tajima’s D (B) were calculated in 10 kb windows with 1 kb step size for K^B and k^y haplotypes in wolves and dogs (see keys). Red horizontal lines in (A) and (B) indicate windows containing the 3 bp deletion. (C) Density distributions of nucleotide diversity calculated from nonoverlapping 1 kb windows for K^B and k^y haplotypes, telomeric regions, and nontelomeric regions in wolves and dogs (see keys). (D) Same as (C) but for Tajima’s D. For each region, the phased sites were concatenated into a single sequence, with telomeric regions ordered from smallest chromosome to largest chromosome.
