This is most marked in chimpanzees and bonobos, which show multimale–multifemale mating structures in which females The African apes, present an anomalous pattern in which females migrate out of their natal communities and join neighboring Among primates ( Dixson 2013), male-biased dispersal and female philopatry are generally the norm and in this context, our closest living relatives, Patterns of dispersal and mating are key factors in determining the distribution of genetic diversity within species ( Dieckmann et al. Species-specific branch length variation that may reflect differences in long-term generation times. Cross-species comparison within a single MSY phylogeny emphasizes the low human diversity, and reveals The western chimpanzee MSY phylogeny has a TMRCA of only 13.2 (10.8–15.8) thousand years, but that for central chimpanzeesĮxceeds 1 million years.
However, particularly marked differences exist among chimpanzee subspecies: Reflecting polygyny versus multimale–multifemale mating. Gorillas and chimpanzees/bonobos present generally low and high MSY diversity, respectively, The two loci show high topological concordance and are consistent withĪccepted (sub)species definitions, but time depths differ enormously between loci and (sub)species, likely reflecting differentĭispersal and mating patterns. We compare these with mtDNA-based trees in the same individuals, estimating time-to-most-recentĬommon ancestor (TMRCA) for key nodes in both cases. Variants and defines unbiased phylogenies. This analysis reveals thousands of novel MSY Orangutans, in which interpretable MSY sequence ranges from 2.61 to 3.80 Mb. Published whole genomes of 24 additional males to yield a total sample of 19 chimpanzees, four bonobos, 14 gorillas, and six Here, we use the human MSY reference sequenceĪs a basis for sequence capture and read mapping in 19 great ape males, combining the data with sequences extracted from the
Of the male-specific region of the Y Chromosome (MSY) has not yet been undertaken. This has previously been investigated by sequencing autosomal and mitochondrial DNA (mtDNA), but large-scale sequence analysis The distribution of genetic diversity in great ape species is likely to have been affected by patterns of dispersal and mating.
