Putative chimpanzee communities (a) and associated Y-chromosome haplotypes (b). a Minimum convex polygons (MCPs) for genotyped samples found in association. Names of putative chimpanzee communities correspond to nearest villages and are listed below the MCP, with Y-chromosome haplotypes found in that putative community listed in parentheses. Underlined names indicate researched communities with preexisting data on approximate community sizes and home range extents. Each community is represented by a unique color. b Median joining network for the 14 Y-chromosome haplotypes. The relative similarity of haplotypes is represented by the lengths of branches, and the relative frequency of occurrence of each haplotype is indicated by the sizes of circles. Colors in haplotype circles correspond to putative communities in (a) exhibiting that haplotype.
