Polymorphism of the mtDNA Control Region in Reindeer (Rangifer tarandus) from the Mainland of the Northeastern Part of European Russia

Abstract

Based on an analysis of the polymorphism of nucleotide sequences (n = 103) of the hypervariable fragment of the mtDNA control region (D-loop), the genetic diversity of wild and domestic reindeer from the mainland of the European Northeast of Russia (eastern parts of Arkhangelsk oblast, Komi Republic, and the Nenets Autonomous Okrug) was studied. Relatively high values of genetic diversity indices were detected. Phylogenetic analysis showed close relationships between reindeer of the study region and those of the tundra zone of Siberia. The influence of domestic reindeer on the formation of the genetic diversity of the wild reindeer was considered as negligible. Genetic lines belonging to an extinct group of forest reindeer from the Nizhny Novgorod region were found among the modern groups of reindeer from the European Northeast of Russia.
