Answer:
Some sweet-pea plants have purple flowers and other plants have white flowers. A homozygous variety of pea that has purple flowers is crossed with a homozygous variety that has white flowers. All the F1 have purple flowers. When these F1 are self-fertilized, the F2 appear in a ratio of 9/16 purple to 7/16 white. Show your work.
A) Give genotypes for the purple and white flowers in the F2 generation.
PP x ww= Pw, Pw, Pw, Pw F1 generation
Pw x Pw= PP. Pw, Pw and ww F2 generation
3 purple and 1 white flower
