A polymorphism of the total protein (MY) and nonspecific esterase (EST) patterns was revealed in the musculocutaneous sac of earthworm Lumbricus rubellus by polyacrylamide gel electrophoresis. The revealed polymorphism is attributed to genetically determined codominant systems, each of which is controlled by the corresponding locus, My and Est, represented(More)
Age-related variation in the absolute and relative weights of the adductor has been studied for 8 years in six samples of the Japanese scallop (Mizuhopecten yessoensis Jay) of different generations from a shellfish farm in Alekseev Bight, Sea of Japan. The test character has proved to vary widely within the samples, with variation in shell size being(More)
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(More)
