dihybrid

1.When a dihybrid is selfed, a characteristic dihybrid ratio of 9:3:3:1 is obtained in the offspring.

用个杂合子交后，后代性状分离的比9：3：3：1。

2.Such interactions between genes lead to apparent deviations from the 9:3:3:1 dihybrid ratio in the F2.

样的之间的关系使得它们的F2代的孟德尔比偏离9：3：3：1。

3.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，那么典型的单杂种和和双杂种的遗传比将在子二代呈现。
