Abstract: | To study the effect of isolation on the genetic variation of mDNA, Salvelinus malma krascheninnikovi and S. malma malma nonanadromous populations from different model ecosystems were examined by RFLI-PCR. The haplotype and nucleotide diversities of mtDNA were significantly decreased in three isolated populations as a result of random gene drift. The genealogy of mtDNA haplotypes was reconstructed. The formation of the modern structure of the isolated populations is discussed in terms of phylogeography. |
