The flower color of the Four-o'clock plant is determined by alleles of genes that demonstrate incomplete dominance. Heterozygotes have an intermediate phenotype of pink flowers while homozygous individuals have either red or white flowers. A plant with red flowers and a plant with red flowers are crossed. If 500 offspring were produced, what number of the F1 offspring would have pink flowers?
