Fig. 7. Ovarian atrophy caused by weak diap1 mutations is rescued by dronc. (A) The diap1^6B/diap1⁸ mutant ovariole is poorly developed and atrophied. (B) By comparison, the dronc^I24 diap1⁸/dronc^L32 diap1^6B double-mutant ovariole shows improved differentiation of nurse cells and advanced maturation of the oocyte. (C) This improvement is visible in a global view of single mutant (left) and double mutant (right) ovaries.
