      Homozygous embryos fail to transform ES organs to CH organs.

      (Liu et al., 1991)

      No embryonic phenotype.

      (Blochlinger et al., 1990)

      Survival less than 1%. Not suppressed by su(Hw)2. Rare surviving males and females are fertile with normal wings, but usually show thoracic protuberances in the region of the presutural and notopleural bristles as are also seen in heterozygotes of ctlS1, Df(1)ct-J4 or Df(1)ct-J6.
