      Detailed Description
      Statement
      Reference

      a7/Df(2R)aEX1 flies have eyes that are significantly smaller than wild-type, and those eyes have rhomboidal ommatidia. The arrangement of photoreceptors within each ommatidium appears wild-type. a7/Df(2R)aEX1 have no detectable phenotype in epithelial development.
