Mendel's Law of Independent Assortment is best illustrated by the F₂ ratio

  1. 3:1
  2. 1:1
  3. 9:3:3:1
  4. 2:1:1
Show answer and 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.
