      Statement
      Reference

      Flies show a block in metaphase (and rarely anaphase). The chromosomes have an abnormal morphology.

      (Omel'ianchuk and Lebedeva, 1998)

      Abnormal mitotic activity as assayed in the larval brain. Highly condensed chromosomes, increased metaphase index with rare anaphase.
