摘要: 采用酸性梯度聚丙烯酰胺凝胶电泳对三河马蛋白酶抑制剂的多态性进行了检测.结果如下:在蛋白酶抑制剂位点共发现11种表型,由6个等位基因PIG、PI1、PIL、PIN、PIS和PIU控制.基因型GL、IL、IN、IS、IU、LN、LS、LU、NS、SU和LL的频率分别为0.04,0.04,0.04,0.04,0.12,0.08,0.16,0.08,0.04,0.04和0.32,其中纯合型LL为优势基因型.等位基因PIG、PII、PIL、PIN、PIs和PIU的频率分别为0.020,0.120,0.520,0.080,0.140和0.120.单位点基因杂合度(H)、个体鉴别概率(Dp)和亲仔关系排除概率(PE)分别为0.674、0.835和0.369.
