Occasionally during meiosis, a mistake can happen whereby a gametemay receive zero or two sex chromosomes rather than one. Bridgesmade a cross between white-eyed female flies and red-eyed male flies.As you would expect, most of the offspring were red-eyed femalesand white-eyed males. On rare occasions, however, he found a whiteeyed female or a red-eyed male. These rare flies were not due to newgene mutations, but instead were due to mistakes during meiosis inthe parent flies.

Question
Occasionally during meiosis, a mistake can happen whereby a gamete
may receive zero or two sex chromosomes rather than one. Bridges
made a cross between white-eyed female flies and red-eyed male flies.
As you would expect, most of the offspring were red-eyed females
and white-eyed males. On rare occasions, however, he found a whiteeyed female or a red-eyed male. These rare flies were not due to new
gene mutations, but instead were due to mistakes during meiosis in
the parent flies. Consider the mechanism of sex determination in fruit
flies and propose how this could happen. In your answer, describe the
sex chromosome composition of the rare flies
