Table 2 Analsis of Molecular Variance (AMOVA) for mtDNA HVRI

From: The population genetics of wild chimpanzees in Cameroon and Nigeria suggests a positive role for selection in the evolution of chimpanzee subspecies

Partition Fixation indices Variance components Percentage of variation Significance

  DRC versus eastern forests (both P. t. schweinfurthii)b

  1. aAMOVA results of data from this study.
  2. bAMOVA analysis reported by Goldberg and Ruvolo [27]. The samples included eastern chimpanzees (P. t. schweinfurthii) divided into two groups of samples recovered from chimpanzees in northeastern Democratic Republic of Congo (DRC) and ‘eastern forests’ that includes sampling locations in Rwanda, Tanzania and Uganda. These two groupings are separated from one another by more than 600km straight-line distance.
