Phenotypic Ratio in Incomplete Dominance

A geneticist is studying a particular trait that exhibits incomplete dominance in a plant species. In this species, a homozygous red-flowered plant (RR) is crossed with a homozygous white-flowered plant (WW), resulting in all heterozygous offspring (RW) that display pink flowers. If these pink-flowered plants are self-fertilized, what phenotypic ratio can be expected in the next generation?
