AMultiple alleles
BIncomplete dominance
CCo-dominance
DPleiotropy
Answer & Solution
Correct answer: B. Incomplete dominance
**Incomplete dominance**: F₁ phenotype is **intermediate** between the two parental phenotypes (pink between red and white). The F₂ ratio becomes **1 red : 2 pink : 1 white** (1:2:1 — phenotype = genotype because heterozygote is distinguishable).
