Summary:[ Objective] To detect the polymorphism of BMPR-IB gene and analyze the relevance between genotype frequency of FecB gene and litter size. [Method] Mutation sites in the BMPR-IB gene of Small Tail Hart sheep were analyzed by PCR-RFLP. [ Resluts] The percentages of individuals with BB, B ＋ and ＋ ＋ genotypes were 24.69%, 54.89% and 20.42%, respectively, and their average litter size per parity was 3.01,2.81 and 2.16, respectively. E Conclusion] The BMPR-IB gene can be used as a molecular genetic marker in fecundity traits. The FecB gene can effectively increase litter size of the Small Tail Han sheep and has additive action on litter size.
