显性等位基因

当一个有机体的一种特性是杂合的，这种特性产生的表现型就只表达显性等位基因额特性。

When an organism is heterozygous for a trait , the resulting phenotype for that trait expresses only the dominant allele .

通常只有其中的一个显性等位基因在表型中表达。

Usually only one of these , the dominant allele , is expressed in the phenotype .

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 .

结果表明，几个杂交F2均代表现为9∶6∶1的分离特征，适合二对独立显性等位基因积加效应的遗传模式。

The results showed that the ratio of separation of F2 from the two resistant resources was 9 ∶ 6 ∶ 1 , and it was apt to the genetic separate mode of the accumulate effect of two pairs of independent dominant genes .

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 .

主要研究性状的高值与隐性等位基因相关，低值与显性等位基因相关。

It also showed that the high value of all characters studied is governed by recessive alleles and the low value by dominant alleles .

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 .

光周期敏感型的引种材料中，显性春化等位基因未发现有明显分布规律。

For the foreign cultivars that were sensitive to photoperiod , the dominant vernalization gene did not present obvious distribution regularity .

请记住，正常等位基因（A）是显性突变等位基因（a）在我们的白化例子，所以这三个基因型能有一两个亮相。

Remember , the normal allele ( A ) is dominant to the mutant allele ( a ) in our albino example , so the three genotypes can have one of two appearances .

正常的等位基因是显性突变的等位基因。

The normal allele is dominant to the mutant allele .

“异位显性：非等位基因的相互作用，尤其是一个基因对另一个基因所表现的显性现象.”

" epistasis : an interaction between nonallelic genes , especially an interaction in which one gene suppresses the expression of another . "

等位基因之间存在显性效应，非等位基因之间存在互作作用。

Dominance effect exists among allele , and interaction exists among non - allelic genes .
