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
purple flowers crossed with a dwarf plant with white
flowers produces 1/2 tall with purple flowers and 1/2
tall with white flowers. What is the genotype of the
parents? What will be an ideal response?
Answer: DD Pp x dd pp
