In Drosophila, genes a and b control body size and color,
respectively. Large body (a+) is dominant over miniature (a), and
gray body (b+) is dominant over ebony (b). The two genes are
located at positions 32.0 and 40.0 on a particular autosome. Note
that crossing-over does not occur in males. A miniature female that
is homozygous for b+ was mated with an ebony male that is
homozygous for a+. All the offspring were phenotypically wild-type
(large body and gray)..
b. What types of offspring would you expect in the F2
generation, and in what percentages?
