      Homozygotes have no ocelli.

      (Serikaku and O'Tousa, 1994)

      Homozygotes have normal, or slightly reduced, eyes but no ocelli.

      (Heitzler et al., 1993)

      Reduction in fibre number in the anterior optic tracts.

      (Hoube and Fischbach, 1992)

      Less extreme than so1. Ocelli absent. Eyes usually normal but sometimes reduced or deformed. Homozygous expression not affected by temperature. At 20o-23oC, so+2/so1 eyes like so+2/so+2. At 27oC, so+2/so1 may resemble so1/so1; eyes range from normal to greatly reduced or deformed. RK2.

      Mutant phenotype can be rescue by introduction of P{hsp70/so} and heat pulses during eye-antennal imaginal disc development.
