  1. From your post, your determination of the F1 generation is unclear. If it is between two homozygous individuals, one yellow and one white, all of F1 will be Wy. F2 will result from the mating of 2 Wy individuals.

    With this information, you should also be able to determine (C).

    I hope this helps. thanks for asking.
