The establishment, maintenance and elaboration of a pattern along a line or a point in an embryo. The establishment, maintenance and elaboration of 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. Polarization of the oocyte along its anterior-posterior axis. An example of this is found in Drosophila melanogaster. The specification of the anterior/posterior axis of the embryo by gradients of maternally-transcribed gene products; exemplified in insects by the morphogens, bicoid and nanos. Subdivision of the embryo along the anterior/posterior axis into anterior, posterior and terminal regions. The specification of the anterior/posterior axis of the embryo by the products of genes expressed maternally and genes expressed in the zygote.
