Fig. 5. slmb mutant clones cause chorion patterning defects. Eggshells were visualized by reflected light or dark-field microscopy. (A) Eggs laid by females with slmb germline clones (right) are often much smaller than wild-type eggs (left). (B) Wild-type dorsal appendage (DA) pattern. (C-F) Egg chambers with slmb somatic clones generate eggshells with variable DA abnormalities, including dorsalized phenotypes (C-E), ramified DA (F), ventralized phenotypes (G,H), and DA shifted to a more posterior position (I), reduced (I,J) or absent (K). In cases where DA are shifted posteriorly (I), the operculum appears enlarged when compared with wild-type eggshells (B); the limits of the opercula are indicated with broken lines.
