共显性等位基因

结果表明，牛乳铁蛋白启动子区在HinfⅠ酶切位点存在多态性，其酶切位点由2种共显性等位基因控制。

The results show that bovine lactoferrin in the promoter region of Hinf ⅰ restriction site polymorphism exists , the restriction site by the two kinds of control of codominant alleles .

结果表明，在EST、PRX和TO酶谱中既有共显性等位基因，又有沉默等位基因的表达；

It was found that there existed both codominant and silent alleles expressed in the zymograms of EST , PRX and TO .

由于HLA复合体具有多个位点的共显性复等位基因系统，故它编码的基因表现出高度的多态性，多态性是HLA基因的重要特性之一，这使HLA可做为基因研究的理想标记物。

HLA complex is a codominant multiple alleles system which has many loci , the genes of it encode show high polymorphism which is a important characteristic of HLA . This make HLA as an ideal mark of gene research .
