General Information
Term embryo ID (Ontology) FBbt:00000052 (Fly Anatomy)
Definition An organism that is undergoing embryogenesis (Campos-Ortega and Hartenstein, 1997). Embryogenesis begins with a fertilized egg, and finishes with hatching at the end of embryonic stage 17 (Campos-Ortega and Hartenstein, 1997).[ FlyBase:FBrf0039741 FlyBase:FBrf0089570 ]
