| 摘 要： | 以874只中国美利奴羊为研究对象,通过对与毛囊发生相关的CTNNB1基因SNP检测,应用SAS软件拟合线性模型,对CTNNB1基因SNP位点与羊毛直径性状进行关联分析。发现CTNNB1基因的819G>A、974A>G等2个位点与羊毛纤维直径显著相关,其中819G>A位点中,GA基因型对羊毛纤维直径是优势基因;974A>G位点中AA对羊毛纤维直径是优势基因型。上述结果为CTNNB1基因819G>A、974A>G位点作为细毛羊羊毛直径性状的分子标记提供了理论依据。

| Abstract: | 874 Chinese Merino sheep were used to examine the SNP(single nucleotide polymorphism)of CTNNB1 gene.A G/A mutation was identified at position of 819G>A in CTNNB1 gene,another A/G mutation was identified at position of 974A>G.The effects of the mutations on the WFB(wool fiber diameter)traits were analyzed.The results showed that genotype GA was dominant for WFD at position of 819G>A.The AA genotype of 974A>G was the dominant genotype for WFD.The two mutations might be good markers for the wool fiber diameter... |
