Y-Chromosome and mitochondrial markers in Macaca fascicularis indicate introgression with Indochinese M. mulatta and a biogeographic barrier in the isthmus of Kra

This is the first report of Y-chromosome introgression between primate species. We sequenced 3.1 Kb of Y-chromosome DNA and 1.5 Kb of mtDNA for 27 macaques of Fooden's (Folia Primatol. [1976] 25: 225-236) fascicularis species group and 5 outgroup taxa (Macaca sylvanus, Papio hamadryas, Theropit...

Description
Summary:This is the first report of Y-chromosome introgression between primate species. We sequenced 3.1 Kb of Y-chromosome DNA and 1.5 Kb of mtDNA for 27 macaques of Fooden's (Folia Primatol. [1976] 25: 225-236) fascicularis species group and 5 outgroup taxa (Macaca sylvanus, Papio hamadryas, Theropithecus gelada, Allenopithecus nigroviridis, and Cercopithecus mona). Phylogenies constructed separately for the paternal and maternal data sets show a Y-chromosome paraphyly among lineages of Macacafascicularis, but a mitochondrial monophyly for the same individuals. The Y-chromosome topology depicts Indochinese Macaca fascicularis haplotypes joining with those of M. mulatta, followed by M. cyclopis and M. fuscata, before clustering with a clade of lineages of M. fascicularis from peninsular Malaysia, Indonesia, and the Philippines. These contrasting patterns of mitochondrial and Y-chromosome DNA, evaluated in the context of the evolutionary consequences of macaque sex-biased dispersal, present strong evidence for contemporary hybridization between Macaca fascicularis and M. mulatta in Indochina and a biogeographic barrier in the Isthmus of Kra.[PUBLICATION ABSTRACT]
