2.
The heterozygote y / y may be distinguished by the nectary color 用蜜腺颜色就可以确定为异质结合的（ y y ） 。
3.
An allele that , in a heterozygote , prevents the expression of another ( recessive ) allele at the same locus 杂合体生物与显性纯合体生物具有相同的表现型。
4.
It revealed that these two transformants were heterozygote , and the foreign gene inserted just to on locus in the plant genome . as the observed ratio of progeny of two transformants which on selfing was 3 : 1 , it was proved to be heterozygote for two transformants 其中2棵抗性株自交后代的遗传分析表明，真空渗入法所得的转化株为杂合体，且其分离比符合3 ： 1的单基因分离规律。
5.
The characteristics of tm - 22 expression presented in transgenic tobacco : 1 ) . virus specificity in either homozygote or heterozygote ; 2 ) tm - 22 gene integrated in tobacco genomic dna with single copy and in inheritance and segregation to progenies on the mendel role ; 3 ) . transgenic line with tm - 22 promoter ( ptm47 ) showed infected symptoms with cell death distinguished to one with 35s promoter ( ptm49 ) after inoculation with tomv - 2a 其次，通过氨基酸序列和结构的比较，确定tm - 2 ~ 2基因的编码蛋白与tomv病毒在抗病反应中相互识别的特异氨基酸及其功能；然后，应用重组dna技术，互换tm - 2 ~ 2基因和tm - 2基因的对应结构域，构建嵌合基因，获得嵌合蛋白表达的转化体，验证tm - 2 ~ 2编码蛋白中变异氨基酸的作用。
