- 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。
- homozygous recessiveness 纯合的隐性
