mnm dominantly suppresses dpp loss-of-function and notch gain-of-function in the eye. (A–F) Scanning electron micrographs of adult compound eyes: dorsal, up; anterior, right and to the same scale (indicated in F). (A) dpp^blk, small, rough eye with very few facets; (B) dpp^blk, mnm^P/dpp^blk, loss of one copy of mnm^P can suppress the small eye size and the eye contains more facets; (C) dpp^blk, mnm^PX1/dpp^blk, the mnm^PX1 null allele strongly suppresses the small eye phenotype; (D) Notch^spl (N^spl), reduced, rough eye with missing or double bristles; (E) N^spl; mnm^P/+ and (F) N^spl; mnm^PX1/+, both the mnm^P and the mnm^PX1 strongly suppress the small-eye phenotype, the null allele to a greater degree.
