Fig. 2. Cuticle preparations of ttv and sotv germline clone embryos resemble hh and wg mutants. The ventral surface of wild-type embryos is marked by bands of denticles separated by naked cuticle (A). Zygotic removal of either wg (B) or hh (C) results in loss of naked cuticle and a lawn of ventral denticles. Embryos lacking maternal and zygotic sotv (D), ttv (E), or both ttv and sotv (F) also show a reduction in naked cuticle. The phenotypes in D-F are of similar severity, but less severe than hh or wg nulls.
