Genotypic Ratios from Incomplete Dominance Cross

Consider a population of flowering plants in which the trait for flower color is determined by a single gene that exhibits incomplete dominance. The alleles involved are R (red) and r (white). When plants have at least one R allele, their flowers appear pink. A researcher conducts a cross between two pink-flowered plants, both heterozygous for the flower color gene (Rr). What is the expected genotypic ratio of the offspring?
