In garden peas, one pair of alleles controls the height of the plant, and a second pair of alleles controls
flower color. The allele for tall (D) is dominant to the allele for dwarf (d), and the allele for purple (P) is dominant to the allele for white (p). A tall plant with white flowers crossed with a dwarf plant with purple flowers produces all tall offspring with purple flowers. What is the genotype of the parents? What will be an ideal response?
