Restriction enzyme analysis of the mitochondrial DNA (mtDNA) fragment encoding subunit 1 of the NADH dehydrogenase complex (ND-1) amplified via polymerase chain reaction (PCR) has been used to obtain data on genetic differentiation of muksun Coregonus muksun (Pallas) populations. Population polymorphism with respect to the restriction sites of 18 endonucleases has been described. It has been demonstrated that the muksun is genetically related to the pidschian C. pidschian (Gmelin), its sympatric species in Siberian waters. Analysis of the median network of mtDNA haplotypes has shown that haplotypes of muksun from various Siberian basins form a common group with haplotypes of pidschian of the Arctic Ocean basin, some frequent haplotypes been found in both forms. This raises the question as to the validity of the muksun as a species. Differences within this group of haplotypes are much smaller than those typical of species of the genus Coregonus. The possibility of a hybrid origin of the muksun from a pidschian-like ancestor and species of the cisco-peled (C. sardinella-C. peled) complex is discussed.
通过聚合酶链反应（PCR）扩增的编码烟酰胺腺嘌呤二核苷酸脱氢酶复合体亚基1（ND-1）的线粒体DNA（mtDNA）片段的限制性内切酶分析，已被用于获取关于穆逊白鲑（Coregonus muksun，帕拉斯）种群遗传分化的数据。已描述了18种内切酶限制性位点的种群多态性。已证明穆逊白鲑在遗传上与皮氏白鲑（C. pidschian，格梅林）相关，皮氏白鲑是其在西伯利亚水域的同域物种。对mtDNA单倍型中位数网络的分析表明，来自西伯利亚不同流域的穆逊白鲑单倍型与北冰洋流域皮氏白鲑的单倍型形成一个共同群体，在两种形态中都发现了一些常见单倍型。这就引发了关于穆逊白鲑作为一个物种的有效性问题。这一组单倍型内的差异远小于白鲑属物种的典型差异。文中讨论了穆逊白鲑可能起源于类似皮氏白鲑的祖先与细鳞大麻哈鱼 - 高白鲑（C. sardinella - C. peled）复合体物种的杂交。
