help with a question on hybrids

timer Asked: Sep 3rd, 2015

Question description

  1. When Mendel crossed two hybrid pea plants whose purebred parents had produced Yellow and Green seeds, he got back a population of offspring plants -- ¾ of those produced Yellow seeds and ¼ produced Green seeds.  If he had crossed the hybrids back to the Green parent plant, what fraction of Green seed producing offspring would he have observed?  (Hint:  this is a cross of a Yy plant with a yy plant).
