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. The offspring of a cross between an RR plant and a WW plant would be(1 point)

red and pink.

Answer 1

In incomplete dominance, the heterozygous genotype produces an intermediate phenotype. In this case, the RR plant (red flowers) crossed with the WW plant (white flowers) would produce offspring with the genotype RW.

Since the RW genotype is heterozygous, it will display an intermediate phenotype, which would be pink flowers.

Therefore, the correct response is:

all pink.
