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.
all pink.

Answer 1

In this case, when you cross a plant with genotype RR (red flowers) with a plant having genotype WW (white flowers), the offspring will be heterozygous (RW). Since the plant species exhibits incomplete dominance, this means that the heterozygous phenotype (RW) will display a blend of the traits from each parent.

Thus, the offspring will all have the genotype RW, resulting in pink flowers.

The correct response is:

all pink.
