In Drosophila, the autosomal genes cinnabar (cn) and brown (bw) control the production of brown and red
Question:
In Drosophila, the autosomal genes cinnabar (cn) and brown (bw) control the production of brown and red eye pigments, respectively. Flies homozygous for cinnabar mutations have bright red eyes, flies homozygous for brown mutations have brown eyes, and flies homozygous for mutations in both of these genes have white eyes. A male homozygous for mutations in the cn and bw genes has bright red eyes because a small duplication that carries the wild-type allele of bw (bw+) is attached to the Y chromosome. If this male is mated to a karyotypically normal female that is homozygous for the cn and bw mutations, what types of progeny will be produced?
