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

Answer 1

In incomplete dominance, the heterozygous offspring display a blend of the traits from both parents. In this case, the RR plant has red flowers, and the WW plant has white flowers.

When these two plants are crossed, the genotype of the offspring will be RW. Since there is incomplete dominance, the RW genotype will exhibit a blend of the red and white flower colors, resulting in pink flowers.

Therefore, the offspring of a cross between an RR plant and a WW plant would be all pink.
