Haplotype network for modern Emu (green) and King Island Emu (red).

<p>Concatenated haplotypes of control and COI regions totalling 2638bp each. The black circle indicates a hypothetical haplotype, the distance between each neighbouring haplotype corresponds to the number of substitutions that separate them. Numbers correspond to positions in the mitochondrial genome as mentioned for <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0018728#pone-0018728-t001" target="_blank">Table 1</a>, underlined numbers represent substitutions that occurred in the cytochrome <i>c</i> oxidase subunit I gene as supposed to the control region.
