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.

the offspring of a cross between an rr plant and a ww plant would be

all white

all pink

red and pink

pink and white

The offspring of a cross between an rr plant and a ww plant in a species with incomplete dominance for flower color would be pink and white. In incomplete dominance, the heterozygous genotype produces an intermediate phenotype that is a blend of the two homozygous phenotypes. Therefore, the offspring would have pink flowers, which is a blend of red and white.
