The number of genes that are necessary to specify a complete developmental network for a fruit fly. Introduction: It is observed that developmental genetics depends on the regulation and expression of a complex network of genes through transcription factors. In Drosophila , such a network is seen to regulate the body plan and the morphological structures of the organism.
