Retinoic X receptor-gamma (RXRG) gene was studied as a candidate gene for the twinning trait of bovine. A new SNP A1941G was detected by sequencing at 3'UTR. Different genotypes were determined in Luxi monotocous cows, Luxi twinning cows, Chinese Simmental cows, Angus cows and Simmental x Mongolia cows by restriction fragment length polymorphism (RFLP). The value of polymorphism information content indicated that this was a moderate polymorphism in Luxi monotocous cows and Luxi twinning cows. The chi(2) test indicated that the polymorphic locus in Luxi twinning cows did not fit Hardy-Weinberg equilibrium (Plt;0.05). The chi(2) test of associational analysis between genotypic distribution and twinning or monotocous trait in Luxi cows showed that the difference was very significant (Plt;0.01). |
