Many of the color varieties of summer squash are determined by two different interacting genes A and B: AA or Aa gives white colored squash, aaBB or aaBb gives yellow squash, and aabb produces green squash.  A plant producing white squash is self-crossed. Three fourths of the offspring produces white squash; one fourth produces green squash. What is the genotype of the parent plant producing white squash?
