Variation of mitochondrial DNA (mtDNA) was examined in nine populations from three lake-river systems of Chukotka and Kamchatka. Significant differences were found between most of the sockeye salmon samples studied. The genetic differences among populations were not high and often did not correlate with the geographical distances between them. The low population divergence is explained by a short time of existence of most of them, having been formed after the recession of the upper Pleistocene glacier. When the populations were grouped according to their spawning biotopes (river or lake), they in general appeared more genetically similar than upon their grouping by geographical location (the lake-river systems). The differences between the river and lake populations in the lake--river systems increased from north to south.
对来自楚科奇半岛和堪察加半岛三个湖河系统的九个种群的线粒体DNA（mtDNA）变异进行了研究。在所研究的大多数红大马哈鱼样本之间发现了显著差异。种群之间的遗传差异不大，且通常与它们之间的地理距离不相关。种群分化程度低的原因是大多数种群形成时间较短，它们是在上新世晚期冰川消退后形成的。当根据产卵生物群落（河流或湖泊）对种群进行分组时，总体上它们在基因上比按地理位置（湖河系统）分组时更为相似。湖河系统中河流种群和湖泊种群之间的差异从北向南增加。
