heterozygote n.【生物學】異型接合體,異型接合子;雜合體,雜合子。

heterozygous

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,通過氨基酸序列和結構的比較,確定tm - 2 ~ 2基因的編碼蛋白與tomv病毒在抗病反應中相互識別的特異氨基酸及其功能;然后,應用重組dna技術,互換tm - 2 ~ 2基因和tm - 2基因的對應結構域,構建嵌合基因,獲得嵌合蛋白表達的轉化體,驗證tm - 2 ~ 2編碼蛋白中變異氨基酸的作用。

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遺傳分析表明,真空滲入法所得的轉化株為雜合體,且其分離比符合3 : 1的單基因分離規律。

An allele that , in a heterozygote , prevents the expression of another ( recessive ) allele at the same locus 雜合體生物與顯性純合體生物具有相同的表現型。

The heterozygote y / y may be distinguished by the nectary color 用蜜腺顏色就可以確定為異質結合的( y y ) 。

The heterozygote y/y may be distinguished by the nectary color . 用蜜腺顏色就可以確定為異質結合的(Yy)。
