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.

Answer 1

In a case of incomplete dominance, when a plant with genotype RR (red flowers) is crossed with a plant with genotype WW (white flowers), the heterozygous offspring (RW) will express a blend of the two phenotypes.

Therefore, all offspring from this cross will exhibit the pink phenotype (the blend of red and white).

So, the correct response is:

all pink.
