| Research Abstract |
We tried to decide the whole mitochondria DNA genome of Yaku Japanese macaque, but it was not successful to do that. So, we make an effort to do same work during one year and decided most of genome, but not completely. We need to continue same work some time. About 9Kb sequences decided by cloning were comparatively illustrated with several other primates in report.
At first we tried to quantify the genetic variability of maicrosaterite DNA level of Yaku Japanese macaque by di-maicrosaterite of 2bp, in this year it is understood for us that the tetra maicrosaterite of 4bp is better marker for quantifying the genetic variability. So we used 14 loci of tetra microsaterite DNA and screened 6 population (l ; Yaku Japanese macaque, 5 ; Japanese macaque) including 212 individuals. Yaku Japanese macaques have not so lower level genetic variability than Japanese macaques, but some kind of their alleles in each locus were not same alleles of Japanese macaque. This phenomenon suggest that the founder population of Yaku Japanese macaque was small, but after that during the process of expanding population, some new mutations of maicrosateraite DNA were accumulated by genetic drift in the population. While Awajishima population which showed low genetic variability have a few same allele as other Japanese macaque, this is explained by isolating history.
