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

The plant species in question exhibits incomplete dominance, which means that when it is heterozygous (having different alleles for a particular trait), neither allele is dominant over the other.
In this case, the RR genotype represents red flowers and the WW genotype represents white flowers. Since these alleles do not have dominance over each other, when a cross is made between an RR plant and a WW plant, the offspring would have a combination of both colors.
Therefore, the correct answer is: pink and white.
