General Information
Term egg ID (Ontology) FBbt:00000034 (Fly Anatomy)
Definition Structure that develops from an oocyte once it has been released from the ovary by ovulation (Qazi et al., 2003). Ovulation triggers egg activation, which alters envelope permeability and causes the resumption of meiosis and translation (Qazi et al., 2003). Fertilization of the egg begins embryogenesis (Loppin et al., 2015).[ FlyBase:FBrf0158848 FlyBase:FBrf0229233 ]
Also Known As "ovum"
