摘要：

利用聚丙烯酰胺凝胶梯度电泳对贵州矮脚黄鸡、兴义矮脚鸡的血清前白蛋白(Pa)、白蛋白(Alb)、后白蛋白(Po)、运铁蛋白(Tf—1,Tf—2)5个位点多态性进行检测。结果表明:除Pa位点在矮脚黄鸡表现为单态,在兴义矮脚鸡表现为多态外,其它4个血清蛋白位点在两鸡种均具多态性,诸位点分别受2～3个(复)等位基因控制。Hardy-Weinberg平衡状态检测结果表明,两群体的Tf—1、Tf—2位点基因型频率都偏离了Hardy-Weinberg平衡状态。兴义矮脚鸡的有效等位基因数和期望杂合度(1.8792,0.4539)较大,矮脚黄鸡(1.7538,0.3772)较小,表明兴义矮脚鸡较矮脚黄鸡的遗传变异度大。

摘要：

In this study,polyacrylamide gel-electrophoresis was employed to investigate the genetic polymorphism of serum protein Alb,Po,Pa,Tf-2,and Tf-1 in Yellow dwarf chicken and Xingyi dwarf chicken.The results showed that there were polymorphisms in the loci of Alb,Po,Tf-2 and Tf-1,but not in Pa of Yellow dwarf chicken.These loci have 2～3 alleles respectively.As for x2 fitness test,it was fur- ther revealed that two loci of Tf-1 and Tf-2 didn't lie in Hardy-Weinberg equilibrium state in both two breeds.It was also observed that the effective number of alleles and the average heterozygosities of serum protein were 1.8792,0.4539 in Xingyi dwarf chicken;1.7538,0.3772 in Yellow dwarf chicken respective- ly.And finally,it was therefore concluded that,the genetic Variance of Xingyi dwarf chicken were higher than that of Yellow dwarf chicken.
