In the garden pea, Mendel studies independent assorting genes and found that purple flowers (P) are dominant over white (p) and axial flowers (A) are dominant over terminal flowers (a). If a pure-breeding white, axial plant is crossed to a pure-breeding purple, terminal plant:
A. What are the genotypes of the P1?
B. What are the phenotypes and ratios predicted in the F1 and F2 from selfed F1? Show your work.
