In snapdragon (Antirrhinum), RR (red) × rr (white) gives F1 plants that are PINK. This pattern is called:
ACodominance, where both alleles fully express
BIncomplete dominance, with intermediate phenotype
CComplete dominance, similar to Mendel's peas
DMultiple allelism present in a single gene
Answer & Solution
Correct answer: B. Incomplete dominance, with intermediate phenotype
Snapdragon flower colour: heterozygote (Rr) shows INTERMEDIATE phenotype (pink) instead of full dominance. F2 ratio: 1 red : 2 pink : 1 white (1:2:1).
