Abstract: The allelic variants of FSH-Receptor (FSHR) gene in cows of different genotypes was determined. Forty-five cows were allotted in groups according to genotype: Bos taurus (n = 15), Bos indicus (n = 15) and Bos taurus x Bos indicus (crossbred; n = 15). The hardy-weinberg equilibrium was determined in the three populations. The gene shown alleles A (243, 63 bp), B (306 bp) and C (243, 150 bp). In the Bos indicus herd, frequencies for genotypes AA and AB were 69 and 28%, respectively, whereas frequencies for alleles A and B were 83 and 17%. In the crossbred herd, frequencies for genotypes AA and AB were 75 and 23%, respectively and frequencies for alleles A and B were 87 and 13%. In the Bos taurus herd, frequencies for genotypes AA, AB and CC were 3, 1 and 64%, respectively, whereas frequencies for alleles A, B and C were 17, 3 and 80%. Hardy-Weinberg equilibrium was found in the Bos indicus and crossbred herds (p>0.05), but not in the Bos taurus herd and in the population as a whole (p<0.05).
