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

all pink.

pink and white.

red and pink.
red and pink.

all white.

Answer 1

In incomplete dominance, the heterozygous phenotype is a blend of the two homozygous phenotypes. In this case, the RR plant has red flowers, and the WW plant has white flowers. The cross between RR and WW will produce offspring with the genotype RW, which would express a pink flower color.

Therefore, the correct response is:

all pink.
