Question 36 Drosophila Experiment In Drosophila melanogaster (also known as fruit flies), wild type flies are normal looking and have no obvious mutations. Wild type traits tend to be dominant to many of the mutations that affect fruit flies. One recessive mutation in particular causes a fly to be born with white eyes. A graduate student working with these flies noticed a white-eyed male fly in his experimental fly population. He bred this fly to several wild type females and in the F1 generation, male and female flies were roughly in equal proportions, and all flies had normal red eyes. The student then allowed the F1 to mate with each other to produce the F2 generation. The F2 generation had mostly red-eyed flies, and some white-eyed flies, but all the white-eyes flies were males. Using XR or R as the dominant allele and X' or r as the recessive allele, what are the possible genotypes of the F1 generation flies? Select all that are possible: OXRY ORR rr OXRXR OX'Y Rr OXRXr
