| 摘 要： | 为了研究青壳蛋遗传规律,我们对青壳蛋鸡进行了四个世代的选育。二、三、四世代产青壳蛋及非青壳蛋母鸡个数分别为205,22;258,17;635,15;与计算出的理论数据206.21;260,15;636,14经卡方检验差异不显著。对一世代、三世代进行测交,其后代产青壳蛋与非青壳蛋母鸡个数分剐为613,463;706,236;与通过一世代、三世代的显性基因频率与隐性基因频率计算出的理论数据600,467;707,235经卡方检验差异不显著。选择加快了群体基因频率的改变,青壳蛋性状确为由一对主效基因控制的完全显性遗传性状。

| Abstract: | The diversity between green-shell-egg hens and non-green-shell-egg hens is not significant which tested by Karphen method.The result is 205,22; 258,17; 635,15 and the theovetical data is 206,21; 260,15; 636,14.The diversity between the green-shell-egg hens and non-green-shell-egg hens which test cross the first and the third generation 613, 463;706,236 and the theoretic data accounted the dominant and recessive gene frequency of the first and the third generation 600,467;707,235 is not significant which tested by Karphen method.The result indicate that population gene frequency variety expedite by selection and the test testify green-shell character is controled by a pair of complete dominant allele. |
