The alleles for eye color in a certain male fruit fly are (r, w). the alleles for eye color in the mating female fruit fly are (r, w). their offspring receive one allele for eye color from each parent. if an offspring ends up with either (w, w), (r, w), or (w, r), its eyes will look white. let x equal the number of offspring having white eyes. let y equal the number of white-eyed offspring having (r, w) or (w, r) alleles. (a) if the total number of offspring is n = 400, how is x distributed?
