Anotace: The research of polymorphism of the PIT-1 and beta-lactoglobulin genes has been provided on the population of Ukrainian brown dairy and Sumy intrabreed type Ukrainian black-and-white dairy cows. The study of genotypes has been carried out using polymerase chain reaction in real time. The existence of interbreed differentiation in the frequencies of genotypes and alleles of the studied genes has been proved. The influence of the studied genes genotype on individual indicators of milk productivity of cows has been established.
