<p>Mean pairwise synonymous diversity (purple, upward pointing lines) and major founding haplotype frequency (orange, downward pointing lines) across chromosome seven. Red points mark regions putatively containing more than two extant founding haplotypes. Values of and major founding haplotype frequency are averaged across overlapping sliding windows (ten kb windows with a two kb slide), here only windows with data for sites of pairwise comparisons are evaluated.
