The genetic structure of the Yakutian cattle breed was studied using the following genes: bPRL (RsaI site in exon 3), bGH (AluI site in exon 5), and bPit-1 (HinfI site in exon 6). The values of observed heterozygosity were 0.37 for bPRL, 0.29 for bGH, and 0.16 for bPit-1. These values are within the range of values for this parameter established for a number of Bos taurus breeds. The results obtained show that genetic variation is preserved in this aboriginal Russian breed, despite a catastrophic reduction of the number of animals.
