| factors shaping genetic variation in the mhc of natural non-human primate populations. | across a large distribution range, population-specific factors as well as pathogen-mediated selection may shape species genetic diversity in the major histocompatibility complex (mhc). we have studied genetic diversity and population differentiation in the mhc region of the southeast asian cynomolgus macaque (macaca fascicularis fascicularis), a species with large and discontinuous range, in order to investigate the role of demography vs selection. genetic variation was assessed at seven mhc mic ... | 2007 | 17854428 |
