General Information
Term anterior/posterior pattern specification ID (Ontology) GO:0009952 (Gene Ontology)
Definition The regionalization process in which specific areas of cell differentiation are determined along the anterior-posterior axis. The anterior-posterior axis is defined by a line that runs from the head or mouth of an organism to the tail or opposite end of the organism.
