Consider that a plant with genotype RR has red flowers and a plant with genotype WW has white flowers. This plant species expresses incomplete dominance for flower color when the plant is heterozygous.

Question

The offspring of a cross between an RR plant and a WW plant would be

Responses

red and pink.
red and pink.

all pink.
all pink.

pink and white.
pink and white.

all white.

Answer 1

In the case of incomplete dominance, when a plant with genotype RR (red flowers) is crossed with a plant with genotype WW (white flowers), the resulting offspring, which would have the genotype RW, will express a phenotype that is intermediate between the two parent phenotypes—in this case, pink flowers.

Therefore, the correct response is all pink.
