Fig. 6. Genetic interactions with mutants in the JAK/STAT and EGFR pathways. DAPI-stained ovarioles from flies doubly heterozygous for da² and: (A) hop², (B,C) Stat92E¹⁶⁸¹, (D) grk^HK36, (E) sos^e4G, (F) phl^c110, and (G) rl^Sem. da² also acts as a dominant enhancer of top^IP02/top¹ (H) and brn^fs.107/brn^1.6P6 (I,J). The ovary interaction phenotypes are indistinguishable from those of da alone, except for the round ovariole morphology with brn.
