Genetics: Analysis and Principles 5th Edition by Robert Brooker

Exercise 27

It seems that developmental genetics boils down to a complex network of gene regulation. Try to draw how this network is structured for Drosophila. How many genes do you think are necessary to describe a complete 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
