Chorion and cuticular phenotypes of lic. Dark-field photographs of chorion (A,B) and embryo cuticles (C–E) preparations of wild type (A,C) and lic eggs or embryos derived from homozygous {hep, lic} germ-line clones (B,D,E). The chorion in B shows a ventralized phenotype as stated by fusion of dorsal appendages. (D) Partial deletion of the A4 abdominal segment indicates a weak abdominal segmentation defect. (E) In extreme cases, the whole abdominal region is deleted and eventually replaced by a single large denticle band. The terminal structures like the head skeleton and the Filzkörpers are normal. Anterior is on the left.
