Q: A pair of fruit flies reproduces and has 1000 offspring. All 1000 of the offspring have the alleles Gg. What is the most likely combination of alleles that each parent has, and why are other combinations not likely?

    Both parents can't be GG, because then all of the offspring would be GG. Both parents can't be gg, because then all of the offspring would be gg. You can't have one parent be GG and the other one be Gg, because some of the offspring would be GG. You can't have both parents be Gg, because some offspring would be GG. So, I think it means that one parent was gg and one was GG.
