      Reference

      Most uex2/uex4 and uex2/Df(2R)247 animals die in the pupal stage or during eclosion. Rare uex2/Df(2R)247 adult escapers exhibit smaller body size, misshapen hind legs and unextended wings within incomplete penetrance - escapers show any combination of these phenotypes and sometimes appear fully wild type.

      A few uex2/Df(2R)34-2 adult escapers exhibit misshapen hind legs.

      uex2/uexL2 animals are viable with hind leg defects.

      uex2/uexLa4 animals are largely viable; some show misshapen hind legs and unextended wings.

      uex2/uexNC9 animals are largely viable with wild type legs and wings.

      (Coulthard et al., 2010)

      Rare hemizygous survivors may have etched tergites and small bodies.

      (Lindsley and Zimm, 1992)

      Hemizygotes are pupal lethal. Adult escapers have unexpanded wings, misshapen third legs, etched tergites and a small body size.
