Abstract

Currently, the relevance of molecular genetic methods for studying animal populations is not in doubt. The article discusses the identification of polymorphic variants of the kappa-casein, somatotropin and thyroglobulin gene in a population of cows of the Alatau breed. The work was carried out using the PCR method with the splitting of amplification products with restriction endonucleases. Allele frequencies were calculated and the results discussed in terms of the formation of animal productive qualities. The binding of the desired alleles in the population according to the results of genetic testing contributes to more rapid genetic progress in animal husbandry.
