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 purple crossed with a tall purple produces 3/4 tall purple and 1/4 tall white. What is the genotype of the parents? What will be an ideal response?
