A cross between true-breeding red (RR) and true-breeding white (rr) snapdragons gives pink F₁ plants. This pattern is best described as
Aincomplete dominance
Bcomplete dominance
Cco-dominance
Depistasis
Answer & Solution
Correct answer: A. incomplete dominance
The heterozygote Rr shows a phenotype (pink) intermediate between the two parental colours, indicating that neither allele completely masks the other. This is incomplete dominance.
