| Term | ommatidial precursor cluster | ID (Ontology) | FBbt:00001770 (Fly Anatomy) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Definition | A cluster of cells in the eye-disc that is the precursor to an adult ommatidium. Eventually there are approximately 750 ommatidial precursor clusters per eye-disc, the first forming at approximately 70hrs before pupation along the morphogenic furrow. A new row of adult ommatidial precursors then emerges from the morphogenic furrow roughly every 1.5 hours.[ FlyBase:FBrf0064798 ] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
