dihybrid
n. [遗]双因子杂种的
英英释义
Noun
- a hybrid produced by parents that differ only at two gene loci that have two alleles each
例句
- When a dihybrid is selfed, a characteristic dihybrid ratio of 9:3:3:1 is obtained in the offspring. 用这个杂合子自交后，后代性状分离的比率为9：3：3：1。
- Such interactions between genes lead to apparent deviations from the 9:3:3:1 dihybrid ratio in the F2. 这样的基因之间的关系使得它们的F2代的孟德尔比率偏离9：3：3：1。
- If the characteristic is governed by simple Mendelian genes, the typical monohybrid and dihybrid ratios become apparent in the F2 generation. 如果其特征取决于单一孟德尔基因，那么典型的单基因杂种和和双基因杂种的遗传比率将在子二代呈现。
- allele dihybrid crosses 等位基因二杂种杂交
- dihybrid cross 双因子杂种杂交
- dihybrid modified 修饰双因子杂种
