[Comparative Estimate of the Sheep Breed Gene Pools using ISSR Analysis].

Using the ISSR-PCR technique, the genetic structure of nine sheep breeds (Ovis aries) bred on the territories of Russia and Mongolia was examined. Species-specific and breed-specific DNA fragments were identified. For the first time, data on the genetic diversity of Telengit and Buubey sheep breeds were obtained.

[Estimation of Genetic Diversity of Romanov Sheep by the Coefficient of Genetic Originality Based on ISSR-Fingerprinting Data].

Estimation of the state of the genetic diversity and the originality of the breed structure is required for the conservation and management of domestic breeds of agricultural animals. The Romanov breed of sheep from the leading breeding and gene pool farms in Yaroslavl oblast (Russia) is the object of our study. ISS R fingerprinting was used as a molecular method of the study of sheep gene pools.

[Comparative analysis of ISSR markers polymorphism in populations of yak (Bos mutus) and in F1 hybrids between yak and cattle in the Sayan-Altai region].

The genetic variability in seven yak populations from the Sayan-Altai region and in F1 hybrids between yak and cattle (khainags) was investigated with the help of a technique that involves the use of inter simple sequence repeat (ISSR) markers generated with PCR primers (AG)9C and (GA)9C. Samples for the analysis were collected in Mongolia, Tuva, and Altai from 2008 through 2012. The examined yak populations differed in in the presence/absence of ISSR fragments, as well as in their frequency.
