Fig. 3. dap oocytes enter the endocycle. (A) Wild-type egg chamber stained with DAPI to highlight nuclei, note the large size of the nurse cell DNA mass relative to the compact oocyte karyosome (arrowhead). (B-D) In dap germline clones, oocytes achieve varying degrees of polyploidy. Egg chambers containing dap germline clones in which (B) there are 16-polyploid nurse cell nuclei and no oocyte, (C) the oocyte is partially polyploid (arrowhead) and (D) the oocyte DNA has abnormal morphology but is not obviously polyploid. The broken circle outlines a magnification of the oocyte defect.
