| 摘要: |
| 本研究采用淀粉凝胶电泳法和聚丙烯酰胺凝胶电泳法对我国七个黄牛品种的四个多态蛋白位点进行了检测,得出了 Hb,Pa,T_r 和 Alp 在各品种中的表现型频率和基因频率。通过标准遗传距离,进行了模糊聚类分析。本文选取λ=0.98为界,将七个黄牛品种按血液蛋白基因位点关系的远近分成四类:秦川牛、晋南牛和南阳牛为一类,郏县红牛和鲁西牛为一类,复州牛和延边牛各自成一类。 |

| Abstract: |
| The starch gel and polyacrylaide gel electrophoresis are adopted to determine the four loci of polyacrylaide in this paper,from which the phenotype and genetic frequencies of Hb,Pa,Tr and Alp in each cattle breed are obtained.The fuzzy cluster analysis is conducted through the standardized genetic distance.With λ=0.98 selected as the border in the paper,the seven kinds of Chinese cattle breeds are divided into four groups based on the relationships of the distance of loci of polymophism:i.e.Qinchuan,Jinnan and Nanyang cattle;Luxi and Jiaxian Red cattle;Fuzhou cattle;and Yanbian cattle. |
