Abstract—

Data on the variability of the mtDNA nucleotide sequence of cytochrome b of pink salmon from successive generations were obtained. There was a higher level of divergence between samples of the line of even years from rivers in different regions than in the successive generation. At the same time, some geographically close populations had statistically significant differences in the genetic parameters. The calculated proportion of intergroup genetic dispersion indicated that the divergence of successive generations of pink salmon occurred in the relatively recent historical past. An analysis of the genetic variability of pink salmon showed that the level of differentiation in populations of the northern Sea of Okhotsk from different fishing grounds was lower than the level observed between the localities within each area. We detected amino acid substitutions in the primary structure of the Cytb protein of pink salmon, indicating the effect of positive stabilizing selection.

俄罗斯东北部部分河流粉红鲑鱼 Oncorhynchus gorbuscha (Walbaum) 的遗传多样性

摘要-

细胞色素b的 mtDNA 核苷酸序列变异性数据获得了连续几代的粉红鲑鱼。不同地区河流的偶数年线样本之间的差异水平高于连续世代。同时，一些地理上相近的种群在遗传参数上存在统计学上的显着差异。计算出的群际遗传离散比例表明，粉红鲑鱼的连续世代的分化发生在相对较近的历史过去。对粉红鲑鱼遗传变异的分析表明，鄂霍次克海北部不同渔场种群的分化水平低于每个区域内观察到的地方之间的分化水平。我们检测到粉红鲑鱼 Cytb 蛋白一级结构中的氨基酸取代，
