| 摘 要： | 利用垂直板型聚丙烯酰胺凝胶电泳法,对76只(雌24,雄52)哈尔滨大白兔红细胞酯酶的遗传多态性进行了研究.结果表明,红细胞酯酶Es-1,Es-2和Es-33个位点各有3种不同的表型AA、AB和BB,它们分别受常染色体上的1对等显性基因A、B控制.各位点的A基因频率分别为0.2829、0.5724和0.5329,B基因频率分别为0.7171,0.4276和0.4671.3个位点的杂合度分别为0.4057,0.4895和0.4978,平均杂合度为0.4643.经X~2检验,这3个位点的基因分布均处于Hardy-Weibery平衡状态(P>0.05).

| Abstract: | Blood samples from 76 (24,52) Harbin White Rabbit were analyzed using vertical plate polyaerylamide gel electrophotesis for studying the genetic polymorphism in the ery-throcyte esterase. Three erythrocyte esterase loci (Es-1,Es-2 and Es-3) were identified to be polymorphic, there were three different phenotypes controlled by 2 autosomal codominant alleles A and B in each locus. The frequencies of A alleles in three loci are 0. 2829, 0. 5724, and 0. 5329,and the B alleles are 0.7171,0. 4276 and 0. 4671 respectively.The heterozygosities for these loci are 0.4057,0. 4895 and 0. 4978 respectively and the average is 0. 4643. The gene distribution of these loci lie within Hardy-Weiberg equilibrium (X2 test P>0. 05). |
