The small linear ridges running along the lateral lines of the cuticle, lengthwise along the body, contain gaps as opposed to a continuous arrangement (Wormatlas).
The eversion process, in which the vulval invagination is turned inside out during the final molt, is disrupted. In C.elegans, such variations in vulval eversion are primarily due to developmental defects in the somatic gonad (and sometimes vulva).
Animals die during embryonic development. In C. elegans, often assayed as refractile eggs that fail to hatch; when applied to large-scale RNAi screens in C. elegans, more than 10% of embryos die.
