| Abstract: | On the basis of sequence analysis of the mitochondrial DNA (mtDNA) control region (CR), cytochrome b (Cytb), and cytochrome oxidase-1 (CoI) genes, the relationships of endemic species Salvelinus andriashevi Berg, 1948, represented by the only population from Lake Estikhed (Chukotka), were estimated. The data on the genealogical analysis of mtDNA haplotypes supported phylogenetic closeness of S. andriashevi and S. taranetzi. It was also demonstrated that the specimens of Chukchi charr, along with Salvelinus sp. 4 (Lake Nachikinskoe), S. krogiusae (Lake Dal’nee), S. boganidae and S. elgyticus (Lake El’gygytgyn), and S. a. erythrinus from Canada’s Northwest Territories (NWT) belonged to the Arctic group of Taranetz charr. The problem of coincidence of taxonomic differentiation of charrs of the genus Salvelinus based on morphological and genetic analyses is discussed. |
