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 six loci and the average loci heterozygosity was 0.2584; and (3) polymorphism existed in marker genes by DNA-RAPD with diversity of 0.4085~0.5318. 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.
