| Research Abstract |
In this study, I examined the amplified fragment length polymorphism (AFLP) as a genome wide genetic marker in evaluation of genetic diversity in primate populations. Although human microsatellite homologues can be applied to non-human primates, the real genetic diversity over the genome of the subject species could not be quantified by the such selected highly polymorphic loci. In this study, firstly I analyzed AFLP and microsatellite DNA polymorphism in Macaca fusucata kept in Primate Research Institute, Kyoto University, and compared population genetic parameters between them to characterize AFLP as the markers, showing that AFLP was comparable to microsatellite markers in detection of genetic differentiation between populations and in clustering the related individuals from a mixed population. Secondary, I analyzed AFLP in hybrid indivisuals between Macaca fuscata and M. cyclopis. The result of principal coordinate analysis of AFLP profiles suggested more complex genetic situation in the F1 hybrid individuals. I analyzed the phylogenetic position of Bornean agile gibbons (Hylobates agilis albibarbis) using mtDNA and TSPY gene sequences, and clarified that it was a sister to Sumatran agile gibbons (H. agilis), not to H. muelleri which inhabit Borneo. In the process of this phylogenetic analysis, I found two mtDNA types ('agilis 1' and 'agilis 2') in H. agilis from Sumatra. The 'agilis 2' type was closely related to the mtDNA of H. lar. AFLP analysis elucidated that H. agilis of 'agilis 2' was not hybrid individuals between H. agilis and H. lar, and that no genetic differentiation existed between the groups of 'agilis 1 ' and 'agilis 2', suggesting the introgression of the lar-like mtDNA ('agilis 2') into a part of Sumatran H. agilis in the past.
