摘  要:
采用垂直聚丙烯酰胺凝胶电泳技术对85只小尾寒羊在转铁蛋白(Tf)位点上的6个生长性状进行了研究.结果表明:Tf位点检出了8种基因型TfAA、TfBB、TfCC、TfAB、TfAC、TfBC、TfCD、TfAD,受4个等位基因TfA、TfB、TfC、TfD控制,其中TfC为优势基因;羊只的6个表型性状在血清转铁蛋白位点的不同基因型之间存在一定的差异,除在体重和体长位点上TfCC型显著大于TfBB型外(P<0.05),其余4个性状均表现为弱相关.据此认为,TfCC型可作为小尾寒羊体重和体长两生长性状早期选种的辅助标记.

摘  要:
The study on 6 growth characters at Tf polymorphism loci of 85 Small-tail Han sheep was carried out with vertical polyacrylamide gel electrophoresis(PAGE).The results showed that there were eight genotypes,TfAA,TfBB,TfCC,TfAB,TfAC,TfBC,TfCD and TfAD,at the Tf loci,they were controlled by four alleles Tf~(A),Tf~(B),Tf~(C)andTf~(D),among which Tf~(C) is the dominant gene.There existed certain phenotype difference among 8 genotypes,the body weight and body length of TfCC genotype were significantly highter than those of the TfBB(P<0.05),the other characters showed an on inferior relevance(P〉0.05).The TfCC genotype may be regared as the assistant mark for early stage selecting on body weight and body length of Smail-tail Han sheep.
