Figure 5.

Mismatch distributions for each major haplotype clade of P. nigromaculata. The abscissa shows the number of pairwise differences between compared haplotypes. The ordinate shows the proportion for each value. Black shows observed frequency distribution while the white bars show the distribution expected under the sudden-expansion model.
