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?

A. Dd Pp x Dd pp B. Dd Pp x Dd Pp C. DD Pp x dd Pp D. Dd pp x dd Pp E. DD Pp x dd pp
