| 摘 要： | 应用扩展的Ｎｅｉ·Ｍ公式对陕西境内４个黄牛群体毛色位点的表型遗传分化进行了研究。结果表明，各总群平均表型异质度与其选种水平密切相关，各总群的表型遗传分化程度与各畜群规模及分布范围有关，各总群遗传变异来源在系统内和系统间存在明显差异，部分表型遗传分化程度较高的指标可作为未来品系育种的研究对象。

| Abstract: | The study on phenotypic genetic differentiation of coat color locus in 4yellow cattle popuiations of Shaanxi was carried out with the extension of Nei.M.for-mula.The result indicated that the average phenotypic heterogenety degree of every gen-ral population is closely related to its selection level;and the phenotypic genetic differ-entiation degree of every general population to its population scale and distribution-scope;the origins of every general population genetic variation has a distinct differenceboth within the system and between systems;some items with higher level of phenotypicgenetic differentiation can be used as the subject for the further study in strain breeding. |
