      Egg chambers arrest at stage S10. The oldest egg chambers contain condensed oligotene nurse cell nuclear chromatin with high ploidy.

      (Keyes and Spradling, 1997)

      Mostly normal eggs and 10% normal embryos.

      Statement
      Reference

      Homozygous females show a strong phenotypic improvement if they also carry one copy of otu11, allowing egg chamber growth to a later developmental stage with more uniform chromatin morphologies, although they are still sterile. 80% of egg chambers in these females are dicephalic.
