“…The observed and expected degrees of genetic heterozygosity and the degree of genetic polymorphism are within the range observed in other primates species (e.g., Selander 1976;Kawamoto et al 1984;Schmitt & Tomiuk 1995). Studies of blood protein polymorphism in vervet monkeys (Cercopithecus aethiops) revealed a similar degree of genetic heterozygosity (H ϭ 0.056) and a similar degree of genetic differentiation in seven small groups of vervet monkeys (F ST ϭ 0.062) (Turner 1981).…”

The genetic polymorphism of natural populations of Lepilemur mustelinus ruficaudatus was studied by protein electrophoresis. We sampled blood from 72 individuals from four populations separated by geographic or anthropogenic barriers from southwestern Madagascar. Six out of 22 enzyme loci showed genetic variation with a degree of polymorphism of 0.273. The expected and observed degree of genetic heterozygosity over all loci is similar to that of other primates (He = 0.058, Ho = 0.036). The F‐statistics revealed that the four subpopulations were similar with respect to gene structure (FST = 0.065, p = 0.016), but the genotypic structures within subpopulations were inconsistent with random mating. For the total of the four subpopulations the proportion of heterozygous individuals was significantly smaller than expected under random mating (FIS = 0.373, FIT = 0.414, p < 0.01). These results correspond closely to what is expected considering the low migration ability of individuals of L. m ruficaudatus leading to small and rather isolated inbred populations.

“…If vervet monkeys originating from across the country are kept in the same enclosures, a mixing of distinct geographical genetic variants may follow, which is to be avoided if the rehabilitated monkeys are to be released at a future date. Apart from the somewhat academic systematic motivation of avoiding the swamping of distinct taxonomic units, such hybridization is also to be prevented if it can affect the survivability of released monkeys (Schmitt and Tomiuk 1994). The latter authors stated that, in captivity, hybridization of monkeys from locally adapted populations can lead to outbreeding depression.…”

2002. Regional genetic variability among South African vervet monkey Chlorocebus aethiops populations. Acta Theriologica 47: 113-124.A South African rehabilitation centre for illegally kept vervet monkeys Chlorocebus aethiops Linnaeus, 1758 required an evaluation of the genetic status of vervet monkeys, to determine whether animals from different geographical areas may be mixed. We studied animals originating from three geographical regions and used biochemical genetic and morphological approaches to address this question. The most prominent trend from allozyme data was derived from the locus Prt-2 (an unspecified serum protein), where each of the three populations could be characterised by the absence or presence of unique alleles. Nevertheless, statistical coefficients indicated little genetic divergence, with genetic distance values of 0.001-0.003 and an overall fixation index value of 0.046. Average heterozygosity did not differ appreciably among populations (2.5-3.3%). The morphological study identified suitable traits, free from the influence of growth allometry, that can be used for inter-population comparisons. No significant morphological differences between con-specific populations were however found. It is concluded that vervet monkeys from the species' wider distribution range is relatively monotypic, but that monkeys from different geographical areas should not be unduly mixed, pending the results of finer grained molecular studies.
