Associations of a HinfI PCR-RFLP of POU1F1 gene with growth traits in Qinchuan cattle.
The objectives of the present study were to estimate the allele and genotype frequencies of the POU1F1/HinfI polymorphisms in beef cattle belonging to four different genetic groups and to determine the effects of these polymorphisms on growth traits in cattle. The 451-bp PCR products of POU1F1 gene digested with HinfI exhibited three genotypes and two alleles, which were at Hardy-Weinberg equilibrium (P > 0.05). Genotype BB was the predominant genotype and B the predominant allele in the studied populations. There was significant difference between Limousin x Qinchuan and Qinchuan in the distribution of genotypes (P < 0.0001). The association of the polymorphism of the POU1F1 gene with growth traits among Qinchuan, Limousin x Qinchuan, Angus x Qinchuan and Germany Yellow x Qinchuan crosses was analyzed. Body weight and wither height of individuals with genotypes AB were higher (P < 0.05)than that of individuals with genotype BB in the Germany Yellow x Qinchua cross, but were not in the other three populations (P > 0.05).
