WebOogenesis, the process of egg production by the ovary (see Chapters 1.2 and 1.3 ), involves a series of sequential stages in which the egg initiates and continues meiosis (which then completes or arrests), fills with RNAs and proteins that will support subsequent embryo development, and acquires a vitelline envelope and chorion (eggshell).
