General Information
Term oogenesis stage S13 ID (Ontology) FBdv:00005278 (Fly Development)
Definition Oogenesis stage that begins when the micropyle begins to form. At the beginning of this stage, about 12-15 nurse cell nuclei remain at the anterior of the oocyte. By the end of this stage, none of these nuclei remain. Oocyte meiosis up to arrest at full metaphase I occurs during this stage.[ FlyBase:FBrf0021038 FlyBase:FBrf0029744 FlyBase:FBrf0034074 FlyBase:FBrf0064777 ]
