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 white.

red and pink.
red and pink.

pink and white.

Answer 1

In this scenario, the red flower color (R) and white flower color (W) exhibit incomplete dominance. This means that when a plant with genotype RR (red flowers) is crossed with a plant with genotype WW (white flowers), the offspring (all heterozygous RW) will exhibit a blend of the two colors.

Therefore, the offspring of a cross between an RR plant and a WW plant would be:

all pink.
