Özet

A total of 177 cattle of four breeds were genotyped for the bovine growth hormone (BGH)-AluI polymorphism by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The genotype and gene frequencies for each breed were determined and tested to be in Hardy-Weinberg equilibrium. According to breeds, frequencies of allele L gene were 0.905 for Brown Swiss, 0.898 for Holstein, 0.976 for East Anatolian Red and 0.893 for Turkish Grey Breeds. The allele L was predominant and variant VV was not detected in the breeds studied. BGH-AluI genotypes were found to be in equilibrium within and among breeds.
