Genetic structure and character of Chaidamu goats were studied through simple random sampling. Genetic structure was analysed from five aspects, and phylogeny status was also investigated. The results indicated that: (1) the average phenotypic heterogeneity degree of coat color and morphological character were 0.3419 and 0.5207, respectively; (2) polymorphous blood albumen existed in 6 loci and the average loci heterozygosity was 0.2584; and (3) polymorphism existed in marked genes by DND-RAPD with diversity of 0.4085 approximately 0.5318. Phylogeny status was investigated through clustering by Ward's method on Chaidamu Goats and other domestic goats. All these indicated that Chaidamu Goats was a domestic goat with less intensively selected breed.
采用简单随机抽样方法对柴达木山羊的遗传结构和特性进行了研究。从五个方面分析了遗传结构，并对其系统发育地位进行了研究。结果表明：（1）毛色和形态特征的平均表型异质性程度分别为0.3419和0.5207；（2）6个位点存在多态性血清蛋白，平均位点杂合度为0.2584；（3）通过DND-RAPD标记基因存在多态性，多样性约为0.4085至0.5318。采用Ward法对柴达木山羊和其他家山羊进行聚类，研究其系统发育地位。所有这些表明柴达木山羊是一个选育程度较低的家山羊品种。
