| 摘 要： | 试验利用PCR-SSCP技术检测了山西马身猪、山西白猪、长白猪、大白猪和杜洛克猪5个品种共490头猪的DE-CR1基因外显子2的多态性。结果显示,DECR1基因外显子2位点存在多态性,表现出AA、BB和AB 3种基因型。群体遗传学分析结果表明,5个猪种都是等位基因B为优势基因;Hardy-Weinberg平衡检验结果显示,山西白猪和杜洛克猪处于平衡状态,山西马身猪、长白猪和大白猪处于非平衡状态;各品种猪的多态信息含量均为中度多态。

| Abstract: | The polymorphisms of the 2,4-dienoyl CoA redutase 1 (DECR1) gene in exon 2 site was detected using PCR-SSCP in 490 pigs of 5 pig breeds including Shanxi Mashen, Shanxi White, Landrace, Yorkshire and Duroc. The results showed that there was a polymorphism in the exon 2 site and three genotypes (AA, BB and AB) were found. Analysis of population genetics suggested that the frequency of B allele was dominant among the studied breeds. The results of Hardy-Weinberg equilibrium test indicated that Shanxi White and Duroc reached the equilibrium. All of the breeds had intermediate polymorphism information contents. |
