1993
Kashtanov, S.N.
The purpose of this research is analysis of supporting heterozygosity mechanisms in caging population of Polar fox (Alopex lagopus L.). The polymorphism of the gene, which codes the blood serum protein - transferrin, was used as a genetic marker. The level of the heterozygosity was studied in the reproductive and young parts of population. As it turned out, the reproductive part is separated on some subpopulations, moreover, inbreeding lead to the decrease of heterozygosity level in this part of population. On the other hand, selection which is to be held by a number of quantitative and qualitative signs in reproductive part of population promote to increase the number of heterozygous animals
