The genetic structure of different sequential generations of mature veined rapa whelk from one biotope

SUMMARY. Allozyme analysis was used for comparison the genetic structure of two different ages veined rapa whelk communities from one biotope (Odessa Bay). Testing of genotypes was performed at 19 loci of nine enzymes. A common feature of the gene pool of Rapana selected samples is a significant genetic disequilibrium and an elevated level of available heterozygosity of polymorphic loci studied (an average of 16–18 %). Different sexually mature generations of mollusks from a single biotope had a relatively lower level of kinship than groups of Rapana venosa individuals from different areas of the Black Sea. It is characteristic that genetic distance between the investigated Rapana populations was at the level of local populations in all cases. The leading role of migrations in the rapa whelks gene pool formation at the waters of Black Sea northern part have been demonstrated by the analysis of the role of evolutionary factors.

Key words: Rapana venosa, population, genetic structure, isozymes
