F in Revision and biogeographical analysis of the black-chinned tilapia Sarotherodon melanotheron (Teleostei, Cichlidae): results of morphometric, allozyme, globin chain and mtDNA studies

F. 5. Unrooted neighbour-joining phylogeny of the 26 different mtDNA haplotypes identified within the sequenced part of the cytochrome b gene (307 bp). Genetic distances were calculated using Kimura's (1980) two-parameter model. The numbers at each node indicate percentage recovery of the particular node (1000 replicates). For abbreviations of haplotypes see table 1.
