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

pink.
The offspring of a cross between an RR plant and a WW plant would have a genotype RW.
To determine the offspring of a cross between an RR plant and a WW plant, we need to understand incomplete dominance.
Incomplete dominance occurs when neither of the two alleles in a heterozygous individual completely dominates the other. Instead, they blend together to produce a phenotype that is an intermediate between the two homozygous phenotypes.
In this case, the RR plant with red flowers and the WW plant with white flowers are both homozygous for their respective alleles. Since the plant species expresses incomplete dominance for flower color, the offspring of their cross would have a phenotype that is a blend of red and white.
Let's denote the red allele as R and the white allele as W. When the RR plant is crossed with the WW plant, all the offspring will be heterozygous Rr, meaning they will carry one red allele and one white allele.
The resulting phenotype of the offspring would be a blend of red and white, often resulting in a pink or light red color.
So, to answer the question, the offspring of a cross between an RR plant and a WW plant would have a pink or light red flower color.
