Abstract

The study included 1083 Polish Holstein-Friesian strain Black-and-White cows. The genetic structure of the herd was determined on the basis of polymorphism within the aromatase gene (CYP 19/Cfr13I and CYP 19/PvuII). Genotypes were identified by the PCR-RELP method. The (CYP 19/Cfr13I allele frequencies were as follows: A-0.86 and B-0.14. The CYP 19/PvuII allele frequencies were as follows: A-0.91, B-0.09. The highest average heterozygosity rate was found in herd A (0.2108). The largest genetic distance eas between cows kept in farms A and C (0.00103).
