[Genetic diversity and phylogenetic relationships among Chinese Macacas based on protein electrophoresis].
In this paper, using protein electrophoresis method, we studied proteinpolymorphism and genetic divergence of 5 species in Genus Macaca: M. mulatta, M. arctoides, M. assamensis, M. thibetana, M. fascicularis. A total of 30 genetic loci were analyzed for 29 individuals, including 4 Nycticebus pygmaeus as outgroup. For the 19 M. mulatta, 9 loci were found to be polymorphic. Accordingly, the percentage of polymorphic loci, P = 0.3; the mean number of alleles, A = 1.4, and the mean heterozygosity, H = 0.1045, indicating a rather high level of genetic diversity in this species. Furthermore, 10 loci showed polymorphic among the 5 species, which can be used as information loci for phylogenetic reconstruction. Three programs (conml, neighbor, fitch) in PHYLIP 3.5 c were chosen to construct phylogenetic trees. All of the three trees show support a close relationship between M. mulatta and M. fascicularis. However, two trees have the same topology, suggesting that M. arctoides belongs to an independent species group, while M. assamensis and M. thibetana are closely related and belong to another species group, and the other tree gives a different topology which implies that M. arctoides, M. assamensis and M. thibetana belong to one species group.
