Median-joining networks of <i>Canis lupus</i> and jackal haplotypes based on cytochrome <i>b</i>.

<p>Circle size and branches are proportional to haplotype frequency and number of mutation steps among haplotypes, respectively. Numbers refer to mutation steps separating the main haplogroups (circled). To improve overall visualization of the network, branch proportions were not respected within the <i>Canis lupus/familiaris</i> haplogroup.
