我们研究了来自撒哈拉以南非洲11个地点的26头狮子的线粒体细胞色素B和NADH脱氢酶亚基5基因（共2,360 bp）的序列变异。六个不同的单倍型观察到的组合序列，形成两个分支：东部和西部稀树草原。乌干达-肯尼亚西部单倍型在基础位置与东部分支的狮子从察沃南部的德兰士瓦和纳塔尔地区。来自克鲁格国家公园南部沙比沙地的单倍型的系统发育位置仍然很难解决。在纳米比亚和博茨瓦纳发现的单倍型形成了西方分支。这里记录的适度遗传变异反对现存非洲狮之间的分类学差异。
We examined sequence variation in the mitochondrial cytochrome b and NADH dehydrogenase subunit 5 genes (2,360 bp total) for 26 lions from eleven locations throughout sub-Saharan Africa. Six distinct haplotypes were observed in the combined sequences, forming two clades: the eastern and the western savannas. The Uganda-Western Kenya haplotype grouped at a basal position with the eastern clade of lions from Tsavo south to the Transvaal and Natal regions. The phylogenetic position of the haplotype from Sabi Sands in the southern part of Kruger National Park remained poorly resolved. The haplotypes found in Namibia and Botswana formed the western clade. The modest genetic variation documented here argues against taxonomic distinctions among living African lions.
