Formation and/or maintenance of a lineage boundary between anterior and posterior compartments that cells cannot cross, thus separating the populations of cells in each compartment. The establishment, maintenance and elaboration of the anterior/posterior axis of the genital disc. An anterior and posterior compartment form in each of the three genital disc primoridia (the female genital disc primordium, the male genital disc primordium and the anal primordium). The establishment, maintenance and elaboration of the anterior/posterior axis of the wing disc, a precursor to the wing. The establishment, maintenance and elaboration of the anterior/posterior axis of the leg imaginal disc. The process whose specific outcome is the progression of the imaginal disc over time, from its formation to the metamorphosis to form adult structures. Imaginal discs are epithelial infoldings in the larvae of holometabolous insects that develop into adult structures (legs, antennae, wings, etc.). The pattern specification process by which an axis or axes is subdivided in space to define an area or volume in which specific patterns of cell differentiation will take place or in which cells interpret a specific environment. The regionalization process by 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. The establishment, maintenance and elaboration of the anterior/posterior axis of the imaginal disc. Imaginal discs are epithelial infoldings in the larvae of holometabolous insects that rapidly develop into adult appendages during metamorphosis from larval to adult form. The regionalization process that results in defined areas of the imaginal disc that will undergo specific cell differentaiton. Imaginal discs are epithelial infoldings in the larvae of holometabolous insects that develop into adult appendages (legs, antennae, wings, etc.) during metamorphosis from larval to adult form.
