Association of Polymorphisms in Fecundity Genes of GDF9, BMP15 and BMP15-1B with Litter Size in Iranian Baluchi Sheep
BMP15 BMP15-1B GDF9 Litter Size Baluchi Sheep
2016/5/6
The incidence of mutation in three loci of GDF9, BMP15 and BMP15-1B and their effects on litter sizes was evaluated in Baluchi sheep. Wild-type alleles were detected for BMP15 and BMP15-1B loci and al...
摘要
以绵羊BMP15基因和BMPR-IB基因为候选基因，以湖羊、中国美利奴单胎品系、中国美利奴肉用和毛用多胎品系为研究对象，采用PCR-RFLP方法对候选基因进行单核苷酸多态性（SNP）位点检测和基因型分析，同时研究基因对绵羊产羔数的影响。对BMP15基因进行SNP检测，结果未发现多态性位点；对BMPR-IB基因进行多态性检测，结果发现了一个A746 G SNP位点。依据A746 G SNP位...
