재래한우의 혈청단백질 좌위의 유전적 다형분석 = Analysis of Genetic Polymorphisms on the Serum Protein Loci in Hanwoo(Bos taurus coreanae)

다국어 초록 (Multilingual Abstract)

The study was carried out in order to investigate the genetic polymorphism of serum protein, Albumin(Al) and Transferrin(Tf) through polyacrylamide gel electrophoresis (PAGE) in native Hanwoo.
Blood samples were collected and examined from a total of 90 cattle raising in Yesan district in Chungnam province.
The results obtained were as follows;
1. The distributions of genotype for Al AA and Al AB at Al loci were 96.7%(87 heads), and 3.3%(3 heads), respectively. The homozygous genotype, Al BB was not detected in this experiment.
2. The frequencies of genes for AlA and AlB were 0.983 and 0.017, respectively. Therefore, these population of Hanwoo group had been maintaining genetic equilibrium (P>0.05).
3. The distributions of genotype for Tf AA, Tf AD1, Tf AD2, Tf AE, Tf D1D1, Tf D1D2, Tf D1E Tf D2D2 Tf D2E, and Tf EE were 10.0%, 23.3%, 20.0%, 6.7%, 6.7%, 13.3%, 6.7%, 3.3%, 6.7%, and 3.3%, respectively.
4. The frequencies of genes for TfA, TfD1, TfD2, and TfE were 0.350, 0.284, 0.233, and 0.133, respectively.
5. Al loci were supposed to be controlled by to autosomal codominant allelic genes such as AlA and AlB. However, Tf loci were assumed to be controlled by four codominant allelic genes as TfA, TfD1, TfD2, and TfE.
