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 (1 point) Responses red and pink. red and pink. all pink. all pink. pink and white. pink and white. all white.

The offspring of a cross between an RR (red flowers) plant and a WW (white flowers) plant, with incomplete dominance for flower color, would be all pink.
