Special traits of the genetic structure and origin of the population of vendace Coregonus albula of Pleshcheyevo Lake

Abstract

Nucleotide sequences of two regions of mitochondrial DNA are analyzed, that of the ND1-fragment and that of the fragment comprising a part of the cytochrome c oxidase gene. In the population of the vendace Coregonus albula from Pleshcheyevo Lake, there are specimens possessing haplotypes considerably differing from common variants of sequences represented both in the water body under consideration and in other water bodies of the European part of Russia. The level of intrapopulation polymorphism exceeds the level between species.
