The process that results in the patterns of cell differentiation that will arise in an embryo. 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 specification of the anterior/posterior axis of the embryo by products of genes expressed in the zygote; exemplified in insects by the gap genes, pair rule genes and segment polarity gene cascade. Specification of the borders of terminal gap gene expression mediated largely by the effects of other gap genes. 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 activation of genes encoding transcription factors at the anterior and posterior ends of an insect embryo by a combination of maternal regulatory signals and interactions among themselves; exemplified by the activation of expression of the Drosophila tailless and huckebein genes. 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. The specification of the anterior/posterior axis of the embryo by the products of genes expressed maternally and genes expressed in the zygote.
