What is the phenotypic ratio in the F2 generation of a dihybrid cross if the traits show incomplete dominance?

A9:3:3:1

B1:2:1:2:4:2:1:2:1

C1:2:1

D3:1

✓ Correct Answer: B — 1:2:1:2:4:2:1:2:1

When incomplete dominance or codominance occurs in both traits, the phenotypic ratio matches the complex genotypic ratio.
