Genetic Changeability by Loci COI mtDNA for Different Coloring of Shell Phenotypes of Black Sea Mussel Mytilus galloprovincialis Lam. (Mollusca: Bivalvia: Mytilidae)

Abstract

The variability of the nucleotide sequences of the fragment of the COI gene of the female genome was studied in four phenotypic groups of the Black Sea mollusk Mytilus galloprovincialis. It was shown that the parameters of genomic diversity (the number of haplotypes, haplotypic and nucleotide diversity, and the number of nucleotide substitutions, including pairwise ones) in mussels with dark shell color are significantly higher than in individuals with light color phenotypes. The revealed differences are related to the peculiarities of ecological preferences of mussels with dark and light shells.
