The development of an organism — from a fertilized egg, through embryonic and juvenile stages, to adulthood — requires the coordinated expression of sets of genes at the proper times and in the proper places. Studies of several bizarre mutations in the fruitfly, Drosophila , provided keys to understanding the molecular basis of large-scale developmental plans.

Then "homeotic" genes act on the segments to make the body parts distinct to each segment.
