      Absence of posterior pole plasm, polar granules and pole cells.

      (Lehmann and Nusslein-Volhard, 1991)

      Some ovarioles consist of a structure resembling an abnormally large germarium. Others develop egg chamber but these have poor cell-cell adhesion and variable morphology. Homozygous females lay no eggs.
