dominant allele

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

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。

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

通常只有其中的一个显性等位基因在表型中表达。

The dominant allele usually controls the normal form of the gene , while mutations are generally recessive .

显性基因通常控制基因的一般形式，而突变通常是隐性的。

The seed coat color is controlled by 2 duplicate loci , with plants having a dominant allele produce black seeds .

种皮颜色由2对独立的基因控制，只要一个位点为显性，种皮就为黑色。

The dominant allele was analyzed , and the results showed that the dominant allele was existed in all loci . 2 .

同时进行优势等位基因分析，结果表明：25个微卫星基因座都有优势等位基因存在。

This mutation result in genotype B change into A. A is the dominant Allele gene in 6 kinds of breed except Thoroughbred horse .

除纯血马外，A基因在各品种中均为优势等位基因，B基因为纯血马的优势基因。

The result indicate that population gene frequency variety expedite by selection and the test testify green-shell character is controled by a pair of complete dominant allele .

选择加快了群体基因频率的改变，青壳蛋性状确为由一对主效基因控制的完全显性遗传性状。

A carrier of Ga gene can pollinate any other corn , but can be only pollinated by a carrier of the same dominant allele .

带有Ga基因的玉米，可使其它材料授粉结实，而其它玉米的花粉却不能使它正常结实，除非带有相同的显性基因；

By analyzing the frequency of dominant allele , it is proved that diagonal crossover and uniform scanning crossover do not cause genetic drift , but occurrence-based scanning crossover induces strong genetic drift that deteriorates with the number of parents increasing .

通过基因频率分析，证明了对角交叉和均匀扫描交叉不会引起遗传漂移，但基于基因频率的扫描交叉可导致遗传漂移，其程度随重组规模的增加而加剧。

Thus organism 's phenotype-its physical appearance and properties-differs from its genotype , which may include both a dominant and recessive allele .

因此，有机体的表现型它的物理表型和性能与它的基因型不同，可能含有一个显性和一个隐性等位基因。

[ WTHZ ] Conclusion RHD 1227A allele is an important genetic marker of Rh DEL phenotype ; RHD 1227A is recessive to normal RHD allele and dominant to RHd allele ;

结论RHD1227A等位基因是DEL表型的重要遗传标记，相对于正常RHD等位基因隐性，而相对于缺失的RHd基因显性；

The normal allele is dominant to the mutant allele .

正常的等位基因是显性突变的等位基因。

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 .

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。
