Abstract

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 by two and four alleles, respectively. The allelic frequency distribution of both loci demonstrated genetic heterogeneity of four L. rubellus samples from Moscow and Moscow Region (311 individuals in total). Allelic frequencies of the revealed loci are proposed as genetic markers for monitoring L. rubellus generations in vermiculture.
