| 摘 要： | 利用26个微卫星标记分析了中国7个地方绵羊（Ovis aries）品种的遗传多样性。通过计算基因频率，平均杂合度（H）、多态信息含量（PIC）及有效等位基因数（Ne），并根据Nei氏标准遗传距离，利用UPGMA法进行了聚类分析，评估其种内遗传变异和品种间遗传关系。结果表明：26个微卫星位点共检测到278个等位基因，Ne在2.1288-13.3924之间；26个位点均为高度多态位点，PIC在0.6628-0.8712之间，聚类分析表明哈萨克羊、阿勒泰羊和巴音布鲁克羊遗传关系最近；然后与白藏羊，黑藏羊聚为一类，湖羊和晋中羊聚为一类，各绵羊各种的聚类关系与其来源，育成史及地理分布基本一致。 |
| 关 键 词： | 绵羊 遗传多样性 遗传距离 聚类关系 |
