| 摘 要： | 为了研究弗莱维赫牛和蒙贝利亚牛POU1F1-exon6多态性与体重、体尺等生长性状指标的相关性,试验采用PCR-RFLP技术分析其多态性,并采用最小二乘法拟合线性模型,对各标记基因型与部分生长性状指标差异显著性进行检验。结果表明:2个群体POU1F1-exon6基因存在2个等位基因A/G,基因频率分别为0.175 9/0.824 1,0.096 8/0.903 2;在该位点上,弗莱维赫牛处于Hardy-weinberg平衡状态(P0.05),而蒙贝利亚牛处于不平衡状态(P0.05);2个群体中AA基因型体重均值高于AG、GG基因型均值(P0.05),GG和AG基因型个体腹围均值高于AA基因型个体均值(P0.05),但在体高、体长、胸围和管围4个性状上无显著性差异(P0.05)。说明POU1F1基因的A15636G位点可以作为牛的体重和腹围指标的候选遗传标记之一。

| Abstract: | To study the correlation of polymorphism of POU1F1-exon6 and growth traits in Fleckvieh and Montbeliarde Cattle,the experiment analyzed the polymorphism by PCR-RFLP technique and adopted linear least squares fitting model to test significant differences between the marker genotypes and growth traits.The results showed that POU1F1-exon6 had two alleles A/G in two populations and the gene frequencies were 0.175 9/0.824 1,0.096 8/0.903 2,respectively.In the sites Fleckvieh cattle were at Hardy-weinberg equilib... |
