摘要
以BMPR-IB基因为策勒黑羊多羔性状的候选基因,采用PCR-RFLP方法对策勒黑羊BMPR-IB基因的多态性进行分析,研究其与产羔数的关系。在随机选取的100只策勒黑羊中BB、B+和++基因型对应的每胎产羔数分别为3.00、2.66和1.98只,BB基因型与B+基因型产羔数极显著高于++基因型(P<0.01),BB基因型与B+基因型之间产羔数差异不显著(P>0.05)。因此,在策勒黑羊中B等位基因对产羔数有显著影响,可以作为分子遗传标记之一用于对策勒黑羊产羔数的选择。
The polymorphism of BMPRIB gene which was one of the candidate genes on the fecundity of Cele black sheep was analyzed by PCR-RFLP method. The relationship between the polymorphism of BMPR-IB gene and litter size was stud- ied. The average litter size of BB,BT and ＋＋ were 3.00, 2.66 and 1.98 respectively in 100 Cele black sheep which were se- lected randomly. The litter size of BB and B＋ were significantly higher more than ＋＋ （P〈0. 01）, but there was no signifi- cant difference between BB and B＋（P〉0.05）. These results indicated that the litter size of Cele black sheep was affected by B allele significantly and it could be used for the selection in Cele black sheep as one of the molecular genetic markers.
