On the ratio of phenotype and genotype of sable and pine marten in sympatry zone in the Northern Urals

Abstract

Analysis of allele frequencies of nine nuclear DNA microsatellite loci in the sable (Martes zibellina) and pine marten (M. martes) demonstrated that these species from allopatric parts of the area differ with a high degree of significance, while hybridization regularly occurs between them in the sympatry zone in the Northern Urals. In total, populations of the sable and pine marten maintain genetic isolation in the sympatry area; however, individual phenotypes do not always correlate with their specific (or hybrid) belonging, which is determined by a genetic method.
