[遗]显性等位基因

dominant role───主要角色

dominant theme───主题

dominant culture───主流文化；主文化；主导文化

dominant force───主导力量

dominant tenement───需役地

dominant wavelength───[光]主波长；[电子]支配彩色的波长

dominant species───[生物]优势种；建群种；优势物种；显性种

Recessive allele : an allele, which only shows in dominant allele is present.───显性基因—不管是在杂合子还是纯合子生物中都表现出性状的基因.

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。

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.

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。

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.
