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，后性状分离比率为9：3：3：1。

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

这样之间关使得它们F2孟德尔比率偏离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.

如果其特征取决于单一孟德尔，那么典型单杂种和和双杂种遗传比率将在子二呈现。
