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

red and pink.

all white.
all white.

all pink.

Answer 1

In a situation where there is incomplete dominance, the offspring of a cross between a homozygous red plant (RR) and a homozygous white plant (WW) will display an intermediate phenotype.

In this case, the RR genotype produces red flowers, and the WW genotype produces white flowers. The heterozygous genotype (RW) will result in a blending of the two traits, leading to pink flowers.

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

all pink.
