神经肽(NPY)基因多态性与邵伯鸡母系繁殖性状的关联性分析
0
()
摘要:
以神经肽(NPY)基因为候选基因,利用PCR-SSCP技术检测该基因的SNPs,并分析基因多态性与邵伯鸡母系母鸡的开产日龄、开产蛋重、开产体重以及300日龄总产蛋数之间的关联性。结果显示,在NPY基因上发现1个SNP位点,带有1对等位基因A和B,基因频率分别为0.35和0.65;不同基因型仅与开产体重性状间有显著相关,表现为基因型AA个体的平均开产体重比基因型AB个体的平均开产体重重119.03 g,且差异显著(P<0.05),基因型AA个体的平均开产体重比基因型BB个体的平均开产体重重47.6 g,但差异不显著(P>0.05);基因型BB个体的平均开产体重比基因型AB个体的平均开产体重重71.43 g,差异显著(P<0.05)。

Relationship of NPY gene''s polymorphisms with reproduction traits in female line of Shaobo chicken
()
Abstract:
In this study,neuropeptideY(NPY) gene was used as a candidate gene to analyze the association of polymorphisms sites with reproduction traits in female line of Shaobo chicken,which included age at first egg(AFE),weight at first egg(WFE),the body weight at first egg(BWFE) and the total number of eggs with 300 age(EN).The result indicated that a SNP site was detected by PCR-SSCP.Frequencies of allele A and B at the SNP site were 0.35 and 0.65,respectively.The significant difference was found only between geno...
