Biochemical Polymorphism and Intraspecific Structure in Populations of Kilka Clupeonella cultriventris (Nordmann, 1840) from Natural and Invasive Parts of Its Range

Аннотация

Study deals with peculiarities of four genetic loci alleles’ distribution in different populations of common kilka from some parts of its range. Geographical differentiation in muscular lactate dehydrogenase-A (LDH-A*) allele frequencies between populations was found. Allele LDH-A*100 frequency is higher in native range. Allele LDH-A*120 prevails in Volga populations of kilka probably due to presence of landlocked freshwater form in historical perspective.
