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 tall plant with purple flowers produces 3/4 tall purple and 1/4 tall white. What is the genotype of the parents?

In mice, the allele for colored fur (C) is dominant to the allele for albinism (c). The allele for normal behavior (W) is dominant to that for waltzing movement (w). Give the probable genotypes of the parents if a colored normal crossed with a white waltzer produced 10 colored normal, 8 colored waltzers, 2 white waltzers, and 11 white normal.
