In the fruit fly Drosophila, a rudimentary wing called “vestigial” and dark body color called “ebony” are inherited at independent loci and are recessive to their dominant wild-type counterparts, full wing and gray body color. Dihybrid wild-type males and females are crossed, and 6400 progeny are produced.

Part A: How many progeny flies are expected to have full wings and gray bodies?

Part B: How many progeny flies are expected to have full wings and ebony bodies?

Part C: How many progeny flies are expected to have vestigial wings and gray bodies?

Part D: How many progeny flies are expected to have vestigial wings and ebony bodies?
