Many insects, like moths and flies, undergo complete metamorphosis. What would you predict about gene expression in these two kinds of insects?
A. The basic organization of homeotic genes is the same in both larvae and adult, but the expression of some other genes must be different. B. Completely different sets of genes must be used in the development of larvae and the adult. C. The order of homeotic genes along the body axis must be different in larvae and adult. D. The same genes are expressed at each stage, but the age and number of cells accounts for the minor morphological differences.
