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. Any developmental process that results in the creation of defined areas or spaces within an organism to which cells respond and eventually are instructed to differentiate. Formation and/or maintenance of a lineage boundary between anterior and posterior compartments of the leg disc that cells cannot cross, thus separating the populations of cells in each compartment. 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. Formation and/or maintenance of a lineage boundary between compartments in an imaginal disc 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 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.
