Mendel's Law of Independent Assortment is best illustrated by the F₂ ratio
A3:1
B1:1
C9:3:3:1
D2:1:1
Answer & Solution
Correct answer: C. 9:3:3:1
Independent assortment predicts the 9:3:3:1 phenotypic ratio in a dihybrid F₂, because each gene segregates independently of the other. Deviation from this ratio (e.g. Morgan's linkage data) shows the law's limits.
