🤓 Based on our data, we think this question is relevant for Professor Molumby's class at UIC.
This cross would be between a pure-breeding white axial (ppAA) and pure-breeding purple, terminal (PPaa) plant.
A. The parental generation, P1, therefore, is ppAA and PPaa
The gametes that will be produced are pA and Pa, respectively.
B. Thus, for the F1 generation, all are heterozygous, and all would be purple, axial (PpAa) plants.
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.
