I'm not asking for anyone to do it for me. I just need someone to expain it to me, but if you know what to do, by all means go right ahead.

You are handed a "mystery" pea plant with long stems and axial flowers, and asked to determine its genotype as quickly as possible. You know the allele for long stems (L) is dominant to that for dwarf stems (l) and that the allele for axial flowers (A) is dominant to that for terminal flowers (a).

1. What are all the possible genotypes for you mystery plant?

2. Describe the one cross you would do, out in your garden, to determine the exact genotype of your mystery plant.

3. While you are waiting for the results of your cross, you go back inside and sit at your desk. You make a seperate prediction of results for each possible genotype listed in part one. How do you do this?

Make these predictions, using the following format: "If the genotype of my mystery plant is _____, the plants resulting from cross will be____."
