Problem 9: Notch wing (N) is a dominant, sex-linked mutant of Drosophila melanogaster (fruit flies) on the X- chromosome. Ebony (ee) body is a recessive, autosomal mutant on chromosome III. Brown (bb) eyes are autosomal recessive on chromosome II. A homozygous notched-wing female is crossed to an ebony-bodied and brown-eyed male. All of the F1 males and females were phenotypically notched wing. The F1 males and females were crossed to produce an F2. At what frequency is a notch, ebony and brown male expected in the F2? O never 01/8 1/64 01/16 O 1/32
