摘　　要：采用中心产区典型群随机抽样方法在山东省济宁市抽取小尾寒羊60只,应用电泳技术检测了11个编码血液蛋白的结构基因座,引用东亚近海大陆的4个绵羊群体的相关资料进行遗传分析。研究表明:(1)5个群体哈拉和林绵羊、乌兰巴托绵羊、小尾寒羊、湖羊、占部落绵羊的基因平均杂合度分别为0 3742、0 3565、0 3184、0 3620和0 2473;(2)前人关于小尾寒羊和湖羊都是由蒙古羊分化而来的考证得到遗传学实验的进一步证明;(3)越南占部落绵羊与山东小尾寒羊关系最近;(4)小尾寒羊、湖羊和占部落绵羊受蒙古羊血统的影响递减。Using the method of random sampling in typical colonies of central area of habitat,60 Small- tailed Han sheep were obtained in Jining city,Shandong Provinec.11 structural gene loci encoding blood protein were detected with electrophoresis techniques.And the related materials of four sheep populations,which were from near- sea mainland in East Asia,were cited to serve as genetic analysis.The results were as follows:(1)The gene average heterozygosity of five populations Kh?Ub?St?Hu?Ct was 0.3742?0.3565?0.3184?0.3620 and 0.2473,respectively.(2)The textual research on that Small- tailed Han sheep and Hu sheep both evolved from Mongolian sheep,obtained by earlier researchers,was further verified with the experiments of genetics.(3)Cham tribe sheep was closest to Small- tailed Han sheep.(4)Small- tailed Han sheep?Hu sheep and Cham tribe sheep were effected by Mongolian sheep bloodline decreasingly.
