Imaginal Discs: The Genetic and Cellular Logic of Pattern FormationMany of the 14,000 genes of Drosophila 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. This book examines the genetic circuitry of the well known 'fruit fly', tackling questions of cell assemblage and pattern formation, of the hows and the whys behind the development of the fly. After an
