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.

这样基因之间关使得它们F2代孟德尔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，那么典型单基因杂种和和双基因杂种遗传将在子二代呈现。
