Fig. 1. Phenotypes of egl-18 chromosomal mutants. (A) Surface view of a wild-type L1 larva. Alae are clearly visible as two unbroken lines along the length of the body. (B) Surface view of an egl-18(n475) L1 larva, showing breaks in alae (arrows) and a twisted body (the basis for the Rol phenotype). (C) Wild-type vulval opening at the `Christmas tree' (L4) stage larva. (D) Defective vulval opening of an egl-18(n475) larva at the L4 stage. (E,F) Adult hermaphrodites, showing the wild-type vulva (E) and the protruding vulva (Pv1) phenotype (F). In these and subsequent photos, anterior is towards the left and dorsal is towards the top.
