Maximum parsimony haplotype network.

<p>Each haplotype is shown as an oval, the size of which indicates the number of individuals with that haplotype (haplotypes within each outcrop are given in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0046351#pone-0046351-t002" target="_blank">Table 2</a>). Mutational steps connecting haplotypes are represented by dashes between haplotypes. NP is shown in grey, NEW in yellow, SEW in red, S in blue and SW in green.
