With the elucidation of the complete fly genome, traditional fly genetics is in more demand than ever. Genetics will lead to an explaination of the role of each of the 14,000 genes, many of which are involved in the development of imaginal discs. These hollow sacs of cells make adult structures during metamorphosis, and their study is crucial to comprehending how a larva becomes a fully functioning fly.
