摘要 以控制Booroola Merino羊多胎性能的BMPR-IB基因作为候选基因,从分子水平上研究新疆多浪羊是否存在该基因的突变。实验结果表明:BMPR-IB基因在多浪羊上存在B+型(突变杂合子),但没有检测到BB型(突变纯合子),多浪羊主要以++型(正常个体)为主,B+型频率为0.35,++型频率为0.65,初步推断可能多浪羊的遗传机制和BooroolaMerino羊相同。 The results show that there are two kinds of genotype(Fec^B/ Fec+, Fec+/Fec+) of BMPR-IB in Duolang sheep, and the genotype frequency are 0.35,0.65 respectively ,but no Fec^B/Fec^B(homozygous) it is deduced preliminarily that there may be a similar genetic mechanism between Bonroola merino and Duolang sheep.
