Abstract

Using four types of markers, the genetic variability of sable and pine marten inhabiting Western Siberia was examined. Izoenzyme and restriction endonuclease analysis of the mtDNA cytochrome b gene fragment, as well as the ISSR-PCR and analysis of microsatellite variation, revealed a low differentiation level of sable and pine marten and confirmed the hybrid origin of atypical representatives of these species. The hybrids were characterized by an increased heterozygosity level and were genetically closer to sable than to pine marten. In atypical martens, the presence of mtDNA haplotypes of eastern sable was identified. This could be the consequence of the reintroduction of the Barguzin sable in the 20th century. In Western Siberia, the introgression of genes between sable and pine marten was massive and symmetrical. It apparently occurred in the past and continues in the present.
