杜洛克杂种猪血浆铜蓝蛋白酶多态性的研究

采用聚丙烯酰胺凝胶垂直平板电泳法对20头杜洛克(父本)杂种猪血浆铜蓝蛋白酶（Cp）多态性进行了研究。结果发现：①被检杜洛克二元、三元杂种猪血浆Cp均有CpAB和CpBB两种基因型，以CpBB 为优势基因型；②被检杜洛克二元、三元杂种猪CpA和CpB基因频率分别为0.1429、0.2308和0.8571、0.7692；③被检杜洛克二元、三元杂种猪的基因杂合度分别为0.2441、0.3350，基因纯合度分别为0.7559、0.6650，有效等位基因数分别为1.3229、1.5038，基因均质度指数分别为0.7152、0.6371。

Investigation on Polymorphism of Plasma Cerum Loplasmin in Duluoke Hybird-pig

20 Duluoke（paternal） Hybird pigs were used to investigate the polymorphism of plasma cerumLoplasmin（Cp）by means of a polyacrylamide gel eletrophoresis in vertical plate.The results were as follows： ①There were both CpAB and CpBB phenotypes on the locus of plasma cerumLoplasmin in Duluoke binary and ternary Hybird pigs examined and CpBB type was a preponderance phenotypes； ②The frequencies of CpA and CpB alleles were 0.1429,0.2308 and 0.8571,0.7692 in Duluoke binary and ternary Hybird pigs examined; ③The gene heterozygosities were separate 0.2441,0.3350，the gene homozygosities were separate 0.7559,0.6650，the numbers of effective allele were separate 1.3229,1.5038 and the gene homozygosity indexes were separate 0.7152,0.6371. 
