| | 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) . | | 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(0.01 0.05)。 | | 文摘来源 | | blood samples werc collcctcd from Erhualian and large white purebred pigs and breeds betweenthem, Level polyareylarnide Gel EIectrophoresis(PAGE ) was applied to study polymorphisms and genetic law ofserum amylase and the influence of its genotype to born weight.There were nine phenotypes of the pig serumamylase found in the current experiment.They were assumed to be controlled by four co-deminant multiple alleles. However,most rcferances reported that amylasc were controlled by three co-dominant multiple a... | | 采集267头二花脸、大约克纯种猪及它们的不同杂交组合后代血样,利用水平聚丙烯酰胺凝胶电泳法,对血清中淀粉酶(Am)的遗传多态型及遗传规律进行研究,并分析了血清淀粉酶型对猪初生重的影响。结果表明猪血清症粉酶表现出多态性,有九种表现型并分别受四个共显性复等位基因控制,而其他文献大多提及Am受三个共显性复等位基因控制,并有六种表现型。Am基因型的九个交配组合后代基因型经X ̄2检验,有两个交配组合(BD×CD,BD×AD)的分离比X ̄2值P<0.01差异极显著;有两个组合(BD×BC,BC×CD)的分离比X ̄2值P<0.05,差异显著;其他五个组合(BD×AC,CD×BB,CD×AB,BD×CC,BC×DD),分离比X ̄2值P>0.05,差异不显著,符合孟德尔遗传规律。有些交配组合分离比与预期比不符合,是否由于某些基因型与生命力有关,还有待于进一步探讨。猪血清淀粉酶型与仔猪初生重相关关系不明显。 | | 文摘来源 | |   |
