A Maximum parsimony median-joining network of domestic pigs and wild boars belonging to subclade 2.

<p>Colors within the nodes: green – domestic pig in URYZ; blue – domestic pig in other regions except URYZ; red - wild boar in URYZ; orange – wild boar in other regions except URYZ. Node sizes are proportional to haplotype frequencies. The link lines between nodes are proportional to the mutation steps. A and B labeled in the plot represent two haplogroups. 2DW2 represents the clade identified in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0051649#pone-0051649-g002" target="_blank">Figure 2</a>. H1, H2 and H3 labeled in the plot represent three core haplotypes: haplotype 1, haplotype 2 and haplotype 3, respectively.
