If the characteristic is governed by simple Mendelian genes, the typical monohybrid and dihybrid ratios become apparent in the F2 generation.

如果其特于单一孟德尔因，那么典型的单因杂种和和双因杂种的遗传比率将在子二代呈现。

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，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。
