  • Specification

    Following fertilization and cleavage, the mass of cells must become specified to each of the types of cells needed to form the whole organism. 

    A summary of mechanisms that can be used to specify cells can be found in the section, The Developmental Mechanics of Cell Specification, from Gilbert's Developmental Biology https://www.ncbi.nlm.nih.gov/books/NBK9968/.

    Germ layers

    In most animals three germ layers are established after fertilization and specification.
