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使得它们的F2代的孟德尔比率偏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.

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。
