| 摘 要： | 目的]建立小尾寒羊高繁品系,检测BMPR-ⅠB基因的多态性,分析FecB基因基因型频率和产羔数的关系。方法]选取小尾寒羊为研究对象,运用PCR-RFLP方法,分析BMPR-ⅠB基因突变位点。结果]样品群中BB、B＋和＋＋基因型比例分别为25.45%,54.46%和20.09%;每胎次平均产羔数分别为3.01只、2.81只和2.16只。结论]FecB基因可以作为小尾寒羊多胎性选育的分子遗传标记,FecB基因能够有效的提高小尾寒羊个体平均产羔数,对产羔数影响呈加性作用。 |

| Abstract: | 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 Tailed Han sheep were analyzed by PCR-RFLP.Result] 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.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 Tailed Han sheep and has additive action on litter size. |
