Polymorphisms of three major genes for reproductive traits in Tibet pigs
藏猪3个繁殖性状主效基因多态性研究

Tibet pig is a special Chinese indigenous pig breed,which could survive in high-altitude areas of Tibet. In the present study,the genotypes of RSR,FSH-,and PRLR gene,the three known major genes of reproductive traits,were identified in 202 Tibet pig individuals. The results showed that the predominant genotypes of RSR,FSH-,and PRLR gene were BB,AB and AA,respectively. The genotype frequencies of the three genes were in Hardy-Weinberg equilibrium. The frequencies of desired alleles of the three genes were higher than those of other alleles,which indicated that Tibet pig had a good potential for improving reproductive traits.
