| 摘 要： | 应用PCR-RFLP分子标记技术,研究了258只滩羊角蛋白KAP1.3基因的多态性及其与裘皮品质的相关性.结果表明,检测出A,B两个等位基因,基因频率分别为53%,47%;产生AA,AB,BB基因型,基因型频率分别为25.2%,55.8%,19.0%;BB基因型所对应的毛股弯曲数显著高于AA,AB基因型（P〈0.05）,AB,BB基因型在A＋194 bp处碱基T转换为C,导致氨基酸由异亮氨酸变异为苏氨酸.可通过改变KAP1.3 BB基因型的频率来提高滩羊裘皮弯曲数目,也说明角蛋白KAP1.3基因有望成为提高裘皮弯曲数性状的分子标记辅助选择候选基因. |

| Abstract: | The study was conducted to find the polymorphism of KAP1.3 gene and the correlation between KAP1.3 gene and fur quality characteristics of Ningxia tan sheep by PCR-RFLP.Alleles A and B were found in the present study,and their gene frequencies were 53% and 47%.Whilst the two alleles generated three different genotypes including AA,AB and BB with the genotype frequencies of 25.2%,55.8%,and 19.0%,respectively.The mean wool curvature marked with BB genotype was significantly higher than others(P<0.05).In addit... |
