您要查找的是不是:
- F1 females could be backcrossed to the male homozygous recessive parent. 也可用雌性F1与隐性纯合雄性亲本回交。
- The kind of mating, using as one parent a known homozygous recessive, is called a testcross. 这种杂交即利用一个已知的纯合的隐性作为一个亲本的杂交,称为测交。
- To distinguish between the phenotypically identical AA and Aa, these can be backcrossed to the homozygous recessive parent aa (a test cross). 为了鉴定表现型完全相同的AA与Aa,我们用纯合的隐性亲本aa来进行回交。
- If a homozygous dominant AA is crossed with a homozygous recessive aa, the F2 generation obtained by selfing the F1 would be 25%AA, 50%Aa, and 25%AA. 如果用纯合的显性基因AA与纯合的隐性基因aa杂交后产生的子一代自交(侧交),则可以得到25%25AA,50%25Aa,25%25aa的子二代。
- only Labs that are ee (homozygous recessive) can be light. 只有当拉拉的基因型是ee(隐性纯合子)才可能是浅色的。
- aa homozygous recessive aa同[种]合子隐性, 纯合子隐性
- homozygous recessive 纯合子隐性
- Have you any plans for the summer recess? 你暑假有什么打算吗?
- A recess, such as a bay or cove, along a coast. 水湾海岸边弯向大陆的凹进处,例如海港或水湾
- Brown eyes are dominant and blue eyes are recessive. 棕色眼睛是显性的,蓝色眼睛是隐性的。
- Homozygous races do not segregate on selfing. 自体受精不能分离纯合的生理小种。
- I push the problem down into the dim recess of my mind. 我把这个问题藏到内心深处,不去多想它。
- The committee is going into recess for a couple of weeks. 委员会打算休会几个星期。
- It applies to duplicate recessive genes. 它适用于双隐性基因。
- The conference will recess till tomorrow morning. 会议暂时休会,明天上午继续开会。
- Genes are described as DOMINANT or RECESSIVE. 基因分为显性基因和隐性基因。
- Most plants carry a large "genetic load" for deleterious recessive genes of which a few are homozygous and depress growth. 多数植物带有大量有害的隐性基因的“遗传负荷”,其中少数是纯合的,因而降低了生长。
- Brown eyes are dominantand blue eyes are recessive. 棕色眼睛是显性的,蓝色眼睛是隐性的。
- These two fruit flies are homozygous for red eye color. 就红色的眼睛而言,这两种果蝇是同型的。
