摘要
本研究通过 1 0个微卫星位点对我国特有的 4个小型猪种 (五指山猪、滇南小耳猪、贵州小型香猪、巴马香猪 )进行了遗传学检测 ,结果表明 :除S0 0 0 3位点表现为单态外 ,其它 9个位点均为高度或中度多态位点 ;4个小型猪种群体内的遗传多样性比较高 ,平均基因杂合度分别为 0 71 65、0 661 1、0 660 2、0 5990 ;多态信息含量在 0 5774～0 6871之间 ;五指山猪与贵州小型香猪的遗传距离较近 ,与滇南小耳猪次之 。
The study was on the Chinese four miniature pigs by using ten micro satellite loci.The result was showed that:9 of the 10 microsatellite loci were medium or high polymorphism,but S0003 was single.The genetic diversity in the four populations was higher,and the average genetic heterozygosity was 0 7165,0 6611,0 6602,0 5990,respectively.The average polymorphism information content was between 0 5774 and 0 6871.The genetic distance between Wuzhishan Pig and Guizhou Miniature Xiang Pig is the nearest and between Wuzhishan and Diannan Xiaoer is nearer.They are all far from Bama Xiang Pig.
