| 摘要: |
| 根据收集的亚洲10国70个家牛群体血红蛋白位点的基因频率，剖析了各家牛总群体的遗传分化程度。结果表明：总群平均基因多样度、基因分化系数、Shannon信息测值及固定指数，都反映出孟加拉国和印度尼西亚两国牛总群体的遗传分化程度较大，印度牛总群体的遗传分化程度较低。各总群的遗传变异来源在亚群内与亚群间分布不同，各总群的等位基因纯合度与其平均有效等位基因数呈明显的反变关系。 |

| Abstract: |
| The gene frequencies of hemoglobin(Hb)locus of 70 domestic cattle populations in the 10 nations of Asia were collected to analyse their genetic differentiation degree. The result showed that average gene heterogenity per total population,coefficient of gene differentiation,Shannon information determination and fixation index all reflected the higher differentiation degree of Bangladash demestic cattle total population and Indonisian domestic cattle total population than that of other nations,and the significant difference of source of genetic variation per total population within the subpopulations and between the subpopulations. There is an opposite relationship between alleles genes homogenety and average effective numbers. |
