Three mitochondrial DNA regions were sequenced in two individuals of the Chukchi charr
Salvelinus andriashevi
from Lake Istihed (Chukotka): the entire gene sequences of cytochrome
b
and cytochrome
c
oxidase-1, and control region. The low level of sequence divergence detected between the sequences suggests that
S. andriashevi
is probably an isolated population of the Taranetz charr
S. taranetzi.
The genealogy of mtDNA haplotypes confirms the phylogenetic closeness of
S. andriashevi, S. taranetzi, Salvelinus
sp. 4 (Lake Nachikinskoe),
S. krogiusae
(Lake Dal’nee),
S. boganidae
and
S. elgyticus
(Lake Elgygytgyn), and
S. a. erythrinus
(NWT).
