| 摘 要： | 采用水平平板聚丙烯酰胺凝胶电泳法,测寻石歧杂鸡的血浆淀粉酶Amy-1~A和Amy-1~B等位基因的频率分别为0.4492、0.5508。成年鸡和18～21日龄死胚中血液淀粉酶表现型频率差异极显著(P<0.01)。死胚中AA型频率高(0.4578),成年鸡中AB型频率高(0.8940),BB型频率在两者中基本相同(0.1022与0.1034)。亲代的血浆淀粉酶型与受精蛋孵化率有关,BB♂× BB♀、BB♂ × AB♀与AB♂ ×AB♀的受精蛋孵化率间差异显著(0.010.05)。

Blood Amylase Polymorphism and Its Association with Embryonic Mortality and Hatchability of Fertilized Egg in Shi Qiza Chicken Population |
| |
| Abstract: | Polymorphism in blood amylase of Shi Qiza, chicken population was determined by horizontal polyacrylamide gel electrophoresis. The frequencies of blood amylase alleles Amy-lA and Amy-1B were 0.4492 and 0.5508 respectively.Significant relationship was found between the blood amylase genotypes and embryonic mortality(P<0.01). The blood amylase genotypes of parents influenced the hatchability of fertilized egg significantly (P<0.05) . |
