Question

Two genes for flower color in snapdragons are red and white. When a red flower is mated with a white flower, all of the offspring have pink flowers. What kind of inheritance must this be?

A.
sex-linked inheritance

B.
dominant

C.
incomplete dominance

D.
recessive

Answer 1

The correct answer is C incomplete dominance, because the pink flowers represent a third phenotype. Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over the other allele which results in the formation of a third phenotype, which in this case is the pink flowers:)
