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

用这个自交后，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使得它们的F2代的德尔比率偏离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.

如果其特征取决于德尔基因，那么典型的基因种和和双基因种的遗传比率将在二代呈现。
