In Drosophila, raspberry eyes (ras) is a sex-linked trait (X chromosome) and recessive. Polished eyes (pol) is autosomal and recessive. A raspberry, polished male is crossed with a homozygous wild-type female, producing an F1 in which both males and females are phenotypically wild-type. The F1 are inbred to form an F2. At what frequency (the number of total flies) would you expect to find a phenotypically raspberry (but not polished) male in the F2? 1. 1/16 2. 3/16 3. 1/4 4. 6/16 5.9/16
