General Information
Term embryonic stage 4 ID (Ontology) FBdv:00005306 (Fly Development)
Definition Nuclear division 10-13. Polar buds divide twice and become tightly grouped at the posterior pole by the end of this stage. Nuclei visible at the rim of the embryo. Stage 4 ends with the beginning of cellularization. Duration at 25 degrees C: approx. 50 minutes (80-130 minutes after egg laying).[ FlyBase:FBrf0089570 ]
Also Known As "syncytial blastoderm" ; "syncytial blastoderm stage"
