Description: Produced by Dr. Thomas Brody of the Society for Developmental Biology and hosted by Purdue University, this site offers users the benefit of a great deal of original research into the genes involved in the development of the fruit fly. Genes are organized three ways: alphabetically, by biochemical function, and by developmental function. Each gene's page begins with summary information and a FlyBase ID, followed by a biological overview, and then sections on gene structure, protein structure, regulation, developmental biology, and finally a list of references. In addition to the genetic information, there are sections on tissue and organ development, and morphogenesis. As Dr. Brody points out, "Currently, Drosophila is the only organism for which one can begin with a list of genes active in the egg and follow the morphological changes and gene interactions through to adulthood." The biological overview for each gene is written with the non-specialist in mind.
