Abstract
The article presents the results of DNA genotyping of sheep of different breeds. It is the first time polymorphism of genes GH-HaeIII and CAST-MspI of replacement sheep of different breeds has been studied and analyzed. The testing results identified specific features of the allele spectrum of the studied genes associated with meat production, expressed in different frequencies of occurrence of both genotypes and alleles. Carrier animals with desirable alleles for breeding were identified in the gene loci under study. Genetic and statistical analysis allows to conclude that the specific weight in the studied populations of sheep of different breeds of particularly valuable genotypes is relatively low. In order to accumulate selection-significant genetic markers in the breeding herds of sheep of different breeds, bred under conditions of the Stavropol Krai and the Republic of Dagestan, regular screening will create conditions for identifying desirable alleles and genotypes, as well as their wide inclusion in the breeding process.
