The dorsal gene in Drosophila is involved in establishing the dorsal-ventral polarity of the embryo. A mutation in the dorsal gene disrupts the normal signaling pathway, leading to the development of embryos that lack ventral structures, as the gene's normal function is to repress the formation of dorsal structures, thereby promoting ventral development.
