Fig 4. Locations of mtDNA and wAlbB haplotype variants.

Pie charts represent mtDNA haplotypes, with the following legend: white = the single common haplotype; yellow = rare haplotype A, 1 SNP; red = rare haplotype B, 3 SNPs; dark grey = rare haplotypes of variable divergence, each confined to one sample site. One SNP in wAlbB was found in three individuals from different sites, these are indicated with a blue ring.
