7. Dumpy wings $$(dp)$$ and brown eyes (bw) are both recessive alleles of Drosophila. Homozygous dumpy flies are bred to homozygous brown flies, yielding all wild-type $$F_1$$ flies. $$F_1$$ females are then bred to dumpy, brown males, yielding equal proportions of four phenotypes. a. Diagram the cross. (1 point) b. What can you say about the dumpy and brown alleles? (Think carefully, there are two possibilities here.) (2 points)
