贵州部分地方鸡品种的血浆酯酶多态性研究

采用水平板聚丙烯酰胺凝胶电泳法，对贵州及河南，广东，江西部分地方鸡品种及有关外来鸡种类共１３个种群、１２２５只个体血浆酯酶－１（Ｅｓ－１）的多态性进行检测。结果：Ｅｓ－１位点存在Ａ、Ｂ和Ｃ３种谱带及ＡＡ、ＡＢ、ＢＢ、ＡＣ、ＢＣ、ＣＣ６种表型（基因型）。各鸡种的表型分布具有明显的地域性特点，同时还可见基因频率与各鸡种的经济用途之间具有一定的关系。Ｘ＾２检验表明，有９个鸡种的表型分布比例极显著偏离了Ｈ

Studies on Polymorphism of Plasma Esterase-1 (Es-1) of Some Native chicken Breeds in Guizhou Province

In this experiment, using the horizontal polyacrylamide gel electrophoresis, we have first detected Polymorphism of plasma esterase-1 (Es-l ) of 4 native chicken breeds in Guizhou (Wumeng, Yellow wumeng blackbone, Black wumeng black-bone, Xiaoxiang black-bone), 2 chicken breeds in Henan(Gushi, Zhengzhou red), 3 chicken breeds introduced to Guizhou (Taihe in jiangxi, Avian and Elisa), and compared with 3 native chicken breeds in Guangdong(Xinghua, Huxu, Qingyuanma) and White Plymouth Rock introduced to Guangdong. It was found that there were three bandings A .B and C in the loci which formed six phenotypes. AA, AB, BB, AC, BC and CC. The phenotype distribution of every chicken breed had notable regional features. And we also can see there were certain relationships between the genes' frequency and every breed's economic uses. It showed through X2-test that in nine of the breeds, the phenotype distribution proportions did notably deviate from the Hardyweinbery's equibilium, especially several breeds of Guizhou province's in which the frequency of AC and BC was very high.
