The season and age-related dependence of the distribution of the frequency of alleles and of five polymorphous loci have been studied for eight cultivated samples of the Japanese scallop M. yessoensis (Jay) from Alexeev Bay (Popov Island, Sea of Japan) using polyacrylamide gel electrophoresis. The consistency of the frequency of alleles and of heterozygotes was revealed for samples with an age greater than one year independently of the season and age. Samples of the younger (11 months) mollusks can have reliable deviations of the frequency of allele and of heterozygotes. However, as the sample reaches a certain age, these genetic parameters correspond to values general to the whole population. The episodic influence of ecological factors on the younger age groups of mollusks is discussed.
利用聚丙烯酰胺凝胶电泳，对来自阿列克谢耶夫湾（波波夫岛，日本海）的8个日本扇贝养殖样本进行了研究，分析了其等位基因频率和5个多态位点分布的季节和年龄相关性。结果表明，年龄大于1岁的样本，其等位基因频率和杂合子频率的一致性不受季节和年龄的影响。较年轻（11个月）的软体动物样本，其等位基因频率和杂合子频率可能存在可靠的偏差。然而，当样本达到一定年龄时，这些遗传参数与整个种群的一般值相对应。文中还讨论了生态因素对较年轻软体动物群体的偶发影响。
