      Detailed Description
      Statement
      Reference

      In mutant embryos, the dorsal medial head epidermis fails to develop as reflected by the presence of a continuous optic placode across the dorsal midline.

      (Chang et al., 2003)

      Embryos are ventralised.

      (Ferguson and Anderson, 1992)

      zen4/Df(3R)Scr embryos show a similar pattern of defects as zen7/Df(3R)Scr embryos. The optic lobe is absent.
