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.

It seems that developmental genetics boils down to a complex network of gene regulation. Try to draw a structure of this network for Drosophila. How many genes do you think are necessary to complete the developmental network for the fruit fly? How many genes do you think are needed for a network to specify one segment? Do you think it is more difficult to identify genes that are involved in the beginning, middle, or end of this network? Suppose you were trying to identify all of the genes needed for development in a chicken. Knowing what you know about Drosophila development, would you first try to identify genes necessary for early development, or would you begin by identifying genes involved in cell differentiation?

provide one example from the Drosophila AP toolkit for "Toolkit genes can be classified according to the phenotypes caused by their mutation. Similar mutant phenotypes often reflect genes that function in a single developmental pathway. Distinct pathways exist for the generation of body axes, for example, and for the formation and identity of fields."

What changes, if any, would you predict would occur in the pigmentation of Drosophila melanogaster with increased global warming? What type of genetic changes would you expect to see? Be as specific as you can.
