Mismatch distribution analysis for total populations of H. bovis and H. sinense using DNASP 5.10. Graphs of the mismatch distributions of (a) H. bovis populations and (b) H. sinense populations. The X axis shows the observed distribution of pairwise nucleotide differences, and the Y axis shows the frequencies. The dotted lines with circles represent the observed frequency of pairwise differences, and the solid lines show the expected values under the sudden population expansion model
