Phenotypic Ratio in Incomplete Dominance Cross

In a laboratory, a scientist is studying a particular gene that affects the coloration of a species of flower. This gene exhibits incomplete dominance, where the heterozygous genotype produces a phenotype that is an intermediate between the two homozygous traits. The scientist crosses two plants: one with red flowers (homozygous dominant) and one with white flowers (homozygous recessive). In the subsequent generation, the phenotype of these hybrids is observed. If the hybrids are then self-fertilized, what is the expected phenotypic ratio of the offspring in the next generation?
