The concentration gradient of the product of the gene responsible for anterior-posterior axis supports the morphogen gradient hypothesis. This hypothesis proposes that morphogens (chemical signals) form concentration gradients and govern cell fate and pattern formation during embryonic development. In this case, the morphogen concentration gradient determines the anterior-posterior axis of the Drosophila embryo.
