Scalloped (sd) wing is an X-linked recessive and ebony (e) body color is an autosomal recessive mutation in Drosophila. If a true breeding scalloped female that is wild type for ebony, is mated with a true breeding ebony male that is wild type for scolloped, what proportion of scalloped, normal body colored males is expected in the F2?
a. 0
b. 1/16
c. 3/16
d. 1/32
e. 1/8

scalloped (sd) is an X-linked recessive and ebony (e) is an autosomal recessive mutation. What proportion of scalloped, ebony females (relative to whole population) is expected in the F2 starting with a true breeding scalloped female which is wild type for ebony mating with a true breeding male mutant only for ebony.

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 4800 progeny are produced. How many progeny flies are expected to have vestigial wings and gray bodies? How many progeny flies are expected to have full wings and gray bodies? How many progeny flies are expected to...

3-3. In the fruit fly, Dichaete (D) is a dominant autosomal mutation that affects wing shape; it is lethal when homozygous. Ebony body, e, and rose eye, r, are recessive mutations also located on the same chromosome. Dichaete flies were crossed to pure-breeding ebony, rose flies. Among the F1 were Dichaete progeny with normal body and eye color. Female Dichaete F1 were test-crossed to ebony, rose males, with the results listed below. (Show your work!) A.
