Figure 4From: Evolution of a behavior-linked microsatellite-containing element in the 5' flanking region of the primate AVPR1AgeneWild chimpanzees are polymorphic for the presence of DupB with short alleles having a prevalence of 0.795 and long alleles 0.205. The graph shows the distribution of genotypes in wild-born chimps of primarily West African origin.Back to article page
