Here, we examined the genetic diversity and phylogeographic structure of domestic goats by determining mitochondrial DNA and microsatellite DNA. The genetic diversity of five goat breeds including Angora goat, Shandonglaiwu black goat, Hanshan white goat, Taihang goat and Wuzhumuqin goat was surveyed using twenty-five microsatellite loci, The UPGMA phylogenetic trees constructed with the Dcoa genetic distances between the five goat breeds supported a closer relationship between Hanshan White goat and Wuzhumuqin goat.

利用微卫星和线粒体DNA分析山羊的遗传多样性及系统进化关系，用25个微卫星位点分析了安哥拉山羊、山东莱芜黑山羊、罕山白绒山羊、太行山羊及乌珠穆沁绒山羊这5个山羊品种的遗传多样性，利用共祖遗传距离的UPGMA聚类表明遗传距离和地理距离是一致的，如内蒙的罕山白绒山羊和乌珠穆沁绒山羊聚到一起。
