Abstract

The aim of the study was to identify the polymorphism of the FGF2 SNP11646 gene (replacement A → G) in intron 1 in the population of sires of JSC Parent breeding enterprise «Elite» of the Vysokogorsky district of the Republic of Tatarstan. As a result of genotyping 67 bulls of dairy and meat breeds of JSC Parent breeding enterprise «Elite» according to the FGF2 gene, two alleles (A and G) and three genotypes (AA, AG and GG) were identified. In this population, there is a predominance of individuals carrying the GG genotype and the G allele. According to the equilibrium balance, the population does not have a genetic equilibrium.
