| 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 ] | ||
