对63只自由生活和圈养的大猩猩的线粒体DNA控制区的高度可变部分进行了测序，其中包括三个公认亚种的代表。这一区域已被证明有助于评估种群中遗传变异的相对水平，澄清野生种群的亚种身份，并检查三个亚种的系统发育关系。东部低地大猩猩(Gorilla Gorilla Graueri)和山地大猩猩(Gorilla Gorilla Beringei)的序列是不同的，但密切相关，每个亚种内的变异性很小。两种目前被隔离的山地大猩猩种群，一种在维龙加斯火山地区，另一种在布温迪森林，用这个线粒体DNA区域进行比较是无法区分的。布温迪森林集团的亚种身份此前一直存在争议。西部低地大猩猩(Gorilla)的线粒体D-loop DNA变异性很高。最分化的大猩猩序列之间的遗传距离大约与黑猩猩(Pantrogrodytes)和矮黑猩猩(Panpaniscus)序列之间的距离一样大。(C)1996年学术出版社。
A highly variable portion of the mitochondrial DNA control region was sequenced in 63 free-living and captive gorillas including representatives of the three recognized subspecies. This region has proven useful for evaluation of relative levels of genetic variability in populations, for clarification of the subspecies identity of a wild population, and for examination of the phylogenetic relationships of the three subspecies. The eastern lowland (Gorilla gorilla graueri) and mountain gorilla (Gorilla gorilla beringei) sequences are distinct but closely related, with low variability within each subspecies. Two currently isolated populations of mountain gorillas, one in the Virungas Volcanoes region and the other in the Bwindi Forest, are indistinguishable using this mitochondrial DNA region for comparison. The subspecies identity of the Bwindi Forest group has previously been debated. Mitochondrial D-loop DNA variability within the western lowland gorillas (Gorilla gorilla gorilla) is very high. The genetic distance between the most divergent gorilla sequences is approximately as great as the distance between sequences of chimpanzees (Pan troglodytes) and bonobos (Pan paniscus).
