[Participation of structural gene markers and anonymous DNA sequences in genetic differentiation in the species Ovis aries L. and Ovis nivicola borealis]. / Ychastie markerov strukturnykh genov i anonimnykh posledovatel'nosti DNK v geneticheskoi differentsiatsii u vidov Ovis aries L. i Ovis nivicola borealis]

Genetic variability and genetic differentiation in two Ovis species--domesticated (Askanian sheep, Sokilska and Kulunda sheep) and wild (bighorn sheep) were analyzed using different types of molecular-genetic markers--genetic-biochemical (30 loci) and DNA (ISSR-PCR) ones. High level of genetic variability was revealed. The average heterozygosity of biochemical markers loci was in range of 0.073-0.188. Markers involved into process of genofond divergence of two closely related species were revealed.

[The genetic structure of Kulunda sheep]. / Geneticheskaia struktura kulundinskoi ovtsy.

The analysis of the genetic structure of the Kulunda sheep in eight polymorphous genetic-biochemical systems was carried out. While comparing with the genetic structures of number of sheep breeds, differentiated by the origin history, productivity traits and the breeding regions, the locus-specificity particularities of the Kulunda sheep were described. The importance of creating of the "genetic portrait" for disappearing breeds was discussed.
