Specific features of polymorphism of GH-HaeIII and CAST-MspI genes in sheep of different breeds

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