      Reference

      Transheterozygotes with stoutTA181 show defects surrounding the dorsal sac. Dorsal bridge is diffuse and occasionally unfused. Strands of sclerotic material are strung out from the anterior vertical plate and ventral side of the dorsal bridge. The H-piece lateral arm is bifurcated and the crossbar widened or broken. Mouth hooks are of normal length but are thin and the bases are often reduced. Third thoracic denticle belt is narrowed. This phenotype resembles that of EcR mutants.

      (Florence and McGinnis, 1998)

      Shows no maternal effect in homozygous germ-line clones.

      Maternal germline clonal analysis demonstrates there is no maternal effect.
