Introduction:
In edible pea, the height is coded by a gene having two alleles. Allele T codes for tall plant and allele t codes for short plant. The color of pods is also coded by a single gene having two alleles. Allele G codes for green pods and allele g codes for yellow pods.

In venetian violets, three phenotypes occur with respect to flower color: a deep violet (almost back), a white, and a pale lavender. Two pale lavender flowered plants have been crossed. The F1 from this cross has individuals with deep violet flowers, with pale lavender flowers, and individuals with white flowers.
A. what are the parent genotypes?
B. what would the expected phenotypic ratio be in these F1 plants?
For the cross: PpAa x PpAa
P = purple flowers (Dominant)
p = white flowers
A = axial flowers (Dominant)
