Mendel's law of independent assortment is best illustrated by which observation?
AF1 plants resemble only one parent
BF2 phenotypes appear in a 3:1 ratio for a single trait
CHeterozygotes show an intermediate phenotype
DTwo traits in a dihybrid cross produce a 9:3:3:1 ratio in F2
Answer & Solution
Correct answer: A. F1 plants resemble only one parent
Independent assortment states that alleles of different genes segregate into gametes independently. Its hallmark is the 9:3:3:1 phenotypic ratio in F2 of a dihybrid cross, derived as the product of two independent 3:1 segregations.
