ON THE GENETIC DIVERSITY OF THE EARTHWORM APORRECTODES CALIGINOSA (SAV) (LUMBRICIDAE)

Distribution of allele frequencies for the polymorphic locus of non-sp ecific esterases of the musculo-cutaneous sac was studied in samples o f Aporrectodes caliginosa from the Moscow District using electrophores is in polyacrylamide gel. The populations of these species were shown to be genetically heterogeneous, even those located in close regions o f the studied part of the range. No correlation was found between the allele frequencies for the studied locus and geographical position of the samples and the ecological conditions of the habitats.
