The process that results in the patterns of cell differentiation that will arise in an embryo. A biological process whose specific outcome is the progression of an integrated living unit: an anatomical structure (which may be a subcellular structure, cell, tissue, or organ), or organism over time from an initial condition to a later condition. 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 establishment, maintenance and elaboration of a pattern along a line or a point in an embryo. The process by which individual somites establish identity during embryogenesis. Specification of the terminal regions (the two non-segmented ends) of the embryo by the gap genes; exemplified in insects by the actions of huckebein and tailless gene products. The hierarchical steps resulting in the progressive subdivision of the anterior/posterior axis of the embryo. The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult). The process whose specific outcome is the progression of an embryo from its formation until the end of its embryonic life stage. The end of the embryonic stage is organism-specific. For example, for mammals, the process would begin with zygote formation and end with birth. For insects, the process would begin at zygote formation and end with larval hatching. For plant zygotic embryos, this would be from zygote formation to the end of seed dormancy. For plant vegetative embryos, this would be from the initial determination of the cell or group of cells to form an embryo until the point when the embryo becomes independent of the parent plant.
