子午岭两侧山羊群体遗传分化研究

Genetic Differentiation of Goat Population in Ziwuling Area

应用随机整群抽样法对地处子午岭东西两侧的两个山羊品种３个层次共计４２类标记特征进行了遗传分析。结果表明，两品种在血液蛋白质及毛色位点的分化程度较低（７％以下），而在形态特征分化程度较高（１８．８４％），进一步综合聚类分析表明，两品种间遗传距离较近（Ｄ＝０．０１６）。

Genetic analysis on 3 class markers with 42 characteristics in 2 goat breeds on the both sides of Ziwuling mountain was carried out with the random cluster samplings.The results showed that the degree of genetic differentiation is lower (less than 7%) on blood protein loci and coat color loci;and higher (18.84% ) on the appearance characters.The further study showed that the genetic distance is short (D=0.016) between 2 breeds.Therefore,it is defined that 2 breeds belonged to the same breed but were differently named.
