Figure S2: Median-joining networks of cytochrome b (cyt b) haplotypes for each of the three Rattus species in South Africa (a) Rattus tanezumi (full-length), (b) Rattus rattus (full-length). The circle size of South African Rattus haplotypes is proportional to the frequency of the haplotype. Haplotype colour coding is consistent with that used in Figure 1, viz. Yellow = south Africa (This study), Green = Africa (Genbank), Grey = Outside Africa (Genbank). Each of the mutational steps separating haplotypes is indicated in blue and corresponds to the relevant position in the cyt b gene, whilst black nodes correspond to median vectors. Haplotype numbers are the same as those provided in Table 1.
