采用不连续垂直板聚丙烯酰胺凝胶电泳技术,对河曲藏獒、青海藏獒、青海藏狮犬和青海土种犬共4个群体103只犬的9个血液蛋白基因座(Tf、Po、Es-1、Es-2、Sα_2:、Hb、Alb、Pr、Amy)的多态性进行了检测,分析了两个藏獒群体的群体内和群体间的遗传变异,并以Nei氏标准遗传距离(D)为基础用UPGMA法探讨了不同犬群之间的遗传关系.结果表明,在4个被测犬群中,Tf、Po、Es-1、Es-2和Sα_2 5个基因座上存在多态性,其中Tf、Es-1和Po分别由3个等住基因所控制,Es-2和Sα_2,分别由2个等位基因所控制,而Hb、Alb、Pr和Amy基因座均呈现单态;河曲藏獒群体内遗传变异较青海藏獒丰富,而两个藏獒群体间的遗传分化程度很低(G_(ST)=0.0187);以Nei氏标准遗传距离(D)为基础的UPGMA法聚类结果表明.青海藏獒与青海藏狮犬和青海土种犬的遗传关系近于河曲藏獒.
採用不連續垂直闆聚丙烯酰胺凝膠電泳技術,對河麯藏獒、青海藏獒、青海藏獅犬和青海土種犬共4箇群體103隻犬的9箇血液蛋白基因座(Tf、Po、Es-1、Es-2、Sα_2:、Hb、Alb、Pr、Amy)的多態性進行瞭檢測,分析瞭兩箇藏獒群體的群體內和群體間的遺傳變異,併以Nei氏標準遺傳距離(D)為基礎用UPGMA法探討瞭不同犬群之間的遺傳關繫.結果錶明,在4箇被測犬群中,Tf、Po、Es-1、Es-2和Sα_2 5箇基因座上存在多態性,其中Tf、Es-1和Po分彆由3箇等住基因所控製,Es-2和Sα_2,分彆由2箇等位基因所控製,而Hb、Alb、Pr和Amy基因座均呈現單態;河麯藏獒群體內遺傳變異較青海藏獒豐富,而兩箇藏獒群體間的遺傳分化程度很低(G_(ST)=0.0187);以Nei氏標準遺傳距離(D)為基礎的UPGMA法聚類結果錶明.青海藏獒與青海藏獅犬和青海土種犬的遺傳關繫近于河麯藏獒.

103 blood samples were taken from four populations of Hequ Tibetan mastiff,Qinghai Tibetan mastiff,Tibetan spaniel and native dogs of Qinghai.Nine blood protein loci(Tf,Po,Es-1,Es-2,Sα_2,Hb,Alb,Pr,Amy)were investigated by using vertical polyacrylamide gel electrophoresis with discontinuous buffer system.Genetic variations were analyzed within and between two populations of Tibetan mastiff.The genetic relationship between dog populations were analyzed by Nei's standard genetic distance(D)and UPGMA.The results showed that genetic variations were observed in Tf,Po,Es-1,Es-2,and Sα_2,others were not polymorphic.There were three alleles at the loci of Tf,Es-1 and Po,two alleles at the loci of Es-2 and Sα_2.The genetic diversities within population of Hequ Tibetan mastiff were richer than that of Qinghai Tibetan mastiff.There was less variation among Tibetan mastiff populations and the genetic differentiation Wag very limited between Tibetan mastiff populations(G_(ST)=0.0187);A dendrogram by Nei's standard genetic distance(D)and UPGMA showed that genetic relationship between Hequ Tibetan mastiff and Qinghai Tibetan mastiff Was distant.
