摘　　要：试验以BMPR-IB的Fec B位点,BMP15基因的B1、Fec XG(B2)、Fec XB(B4)3个位点为阿勒泰羊高繁性状候选基因,采用PCR-RFLP、SSCP技术检测了116只阿勒泰羊上述4个位点的单核苷酸多态性。结果表明:阿勒泰羊Fec B、Fec XG(B2)、Fec XB(B4)位点只存在野生型,无多态性。B1位点检测到AA、AB、BB三种基因型,其基因型频率分别为0.63、0.29、0.08,等位基因A、B的频率分别为0.78、0.22。In this study,the single nucleotide polymorphism of four loci（Fec B of BMPR-IB,B1,Fec XGand Fec XBof BMP15）from 116 Altay sheep were detected using PRC-RFLP,SSCP technique. The results showed that there were no polymorphism in the loci of Fec B,Fec XGand Fec XB,only wild type loci;there were three genotypes（AA,AB,BB）in the loci of B1,their frequencies were 0.63,0.29,0.08 respectively,the frequencies of allele gene A and B were 0.78 and 0.22 respectively.
