“…Interestingly, v.D is the rarest V-A-B-D type in common chimpan-zees, with a frequency of 1.4% (Socha, 1984). A similar pattern has been observed for the R-C-E-F blood group system: common chimpanzees demonstrate at least 20 different types, while bonobos are monomorphic for an R-C-E-F type not observed in common chimpanzees (Moor-Jankowski et al, 1975;Socha, 1984). From an evolutionary perspective, our data and the blood group data (assuming that blood groups have not experienced positive selection) support the hypothesis that a subpopulation of chimpanzees was isolated (i.e., a bottleneck event) south of the Zaire river and became the ''founders'' of P. paniscus.…”

“…Although only additional sampling (either different individuals and/or different loci) will be able to confirm if P. paniscus has a genome-wide reduction in nucleotide diversity, it is worth noting that a similar pattern of reduced variation among bonobos has also been observed among chimpanzee blood groups. For example, 16 various V-A-B-D blood types have been observed in common chimpanzees, while only one type (v.D) has been observed in bonobos (Moor-Jankowski and Wiener, 1965;Moor-Jankowski et al, 1975;Socha, 1984). Interestingly, v.D is the rarest V-A-B-D type in common chimpan-zees, with a frequency of 1.4% (Socha, 1984).…”

One of the primary objectives in the captive management of any endangered primate is to preserve as much as possible the genetic diversity that has evolved and still exists in wild gene pools. The rationale for this is based on the theoretical understanding of the relationship between genetic diversity and fitness in response to selection. There remains little consensus, however, as to the type of genetic data that should be used to monitor captive populations. In order to develop a deeper understanding of the degree and nature of genetic diversity among "wild" chimpanzee gene pools, as well as to determine if one type of genetic data is more useful than others, DNA sequence data were generated at three unlinked, nonrepetitive nuclear loci, one polymorphic microsatellite, and the mitochondrial D-loop for 59 unrelated common and pygmy chimpanzees. The results suggest that: 1) data from nuclear loci can be used to differentiate common chimpanzee subspecies; 2) pygmy chimpanzees may have less genetic diversity than common chimpanzees; 3) shared microsatellite alleles do not always indicate identity by descent; and 4) nonrepetitive loci provide unique insights into evolutionary relationships and provide useful information for captive management programs.

“…We favor the hypothesis of fairly recent divergence for the two species of Pan on the basis of parapatric distribution and morphological, biochemical, and karyotypic similarity [Goodman et al, 1970;Khudr et al, 1973], Low diversity of blood groups [Moor-Jankowski et al, 1975] could be explained by isolation in a small remnant forest block during the arid episodes of the Pleistocene. Such a genetic bottleneck increases the probability of evolutionary change through the random actions of genetic drift and the founder effect.…”

“…Because blood group study of Pygmy chimpanzees undertaken in the past has not uncovered sufficient markers for paternity analysis (Moor-Jankowski et al, 1975), the four animals were studied chromosomally. It had previously been shown that certain chromosomal markers of Pan paniscus exist with expected segregation (Bogart & Benirschke, 1977).…”
