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. The regionalization process that divides an organism or part of an organism into a series of semi-repetitive parts, or segments, often arranged along a longitudinal axis. The process whereby segments assume individual identities; exemplified in insects by the actions of the products of the homeotic genes. The specification of the characteristic structures of trunk segments, following establishment of segment boundaries. In Drosophila, the trunk segments include thoracic segments and abdominal segments A1 to A8. Identity is considered to be the aggregate of characteristics by which a structure is recognized. Partitioning of the blastoderm embryo into trunk segmental units. In Drosophila, the trunk segments include thoracic segments and abdominal segments A1 to A8. The hierarchical steps resulting in the progressive subdivision of the anterior/posterior axis of the embryo. The specification of the characteristic structures of the thoracic segments following establishment of segment boundaries. Identity is considered to be the aggregate of characteristics by which a structure is recognized. The specification of the characteristic structures of the abdominal segments following establishment of segment boundaries. Identity is considered to be the aggregate of characteristics by which a structure is recognized.
