Fig. 1. cic mutant females produce eggs with a range of dorsalized phenotypes. (A) Wild-type egg (lateral view), exhibiting two dorsal appendages separated by an appendage-free dorsal midline region. (B-F) Eggs from cic mutant females, ventral or lateral views, as indicated. Eggs are grouped into five classes according to phenotypic severity. (B) Weak cic eggshell phenotype (lateral view). The dorsal midline region is expanded (arrow) and the appendages are broader and positioned laterally with a trace of ventral collar material (arrowhead). (C) Similar to B, but exhibiting a ventral collar of ectopic appendage-like material. (D) Egg with a thicker ventral collar (arrowhead). Lateral view illustrates that the collar is strictly ventrolateral and does not extend to the dorsal side (arrow). (E) Collar is more pronounced than in D. (F) Similar to E, with small anterior projections. (G-H') Eggs from females with follicle cell clones homozygous for cic^fetU6. (G) Foci of ectopic appendage material are observed in the ventral and lateral anterior region. (H,H') At the extreme anterior, ectopic appendage-like projections can be observed (arrow). H is a dorsal view, H' a ventral view.
