Progress in genetics relies on studies with model organisms. In particular, the fruit fly and Nematodes have taught us a good deal about the role of various kinds of genes in development.Briefly describe one major idea or principle about organism development that has come from studying each of these organisms.Humans are, of course, more complicated than either of these organisms. What allows us to think that at least some of the rules of development learned from these model organisms apply to human beings?
