General Information
Term two cone-cell ommatidial precursor cluster ID (Ontology) FBbt:00001774 (Fly Anatomy)
Definition Ommatidial precursor cluster composed of eight future photoreceptors and two cone cell precursors. The two cone-cell ommatidial precursor stage is defined by the apical arrival of the nuclei of R7 and the anterior and posterior cone-cells. The nuclei of R1 and R6 are displaced basally. R4 loses its apical contact with R8, and R3 contacts R5 (Cohen, 1993).[ FlyBase:FBrf0064789 ]
Also Known As "two cone-cell stage ommatidial cluster"
