The work aims to determine the genotypic structure of populations and the combination of genotypes of cattle of different productivity in individual genes and gene complexes based on the labeling of hereditary information by polymorphic genetic systems, DNA markers, genes of quantitative traits. Research methods - genetic, molecular genetic, immunological, statistical. Research material - selection and genetic processes in herds, parameters and changes of antigens of blood groups, genes and phenotypic structure of genes that control certain economically useful traits of cattle. A method of using genetically determined hereditary information on polymorphic genetic systems has been developed. DNA markers for marking genotypes with certain economically useful traits. Populations of Simmental cattle of domestic and Austrian selection (PJSC Red Breeding Plant PJSC, Kramagrosvit LLC) and Charolais breeds of French and domestic selection (F. Khirlyuk & Co. and DG Gontarivka) were studied. Donetsk regions. The genetic profile of animals (n = 320) of these livestock populations was determined by polymorphic systems of blood groups and genes of quantitative traits (k-casein genome, growth hormone genome, leptin and beta-lactoglobulin genome). Changes in the genetic structure of populations under the influence of applied selection methods are analyzed. Animals of the Simmental breed of domestic and Austrian selection were studied by leptin and beta-lactoglobulin genes. The associative connections of the main productive traits with the polymorphism of the genes kappa-casein, growth hormone, leptin and beta-lactoglobulin were analyzed, the most desirable complex genotypes were determined.
