      Reference

      Scer\GAL4MD-638-mediated expression of the SnooS2 mutant via the P{GSV1} element associated with SnooM67 results in mild wing venation defects.

      Trans-heterozygotes with Df(2L)snoN are fully viable; females are fertile and complete oogenesis normally.

      Discoverer

      Isolated as a partial revertant of the severe wing phenotype induced by Scer\GAL4MD-638-mediated expression of SnooM67, in which Snoo is expressed from its endogenous locus.

      (Barrio et al., 2007)

      Separable from: P{GSV1}SnooM67.

      (Barrio et al., 2007)

      Separable from: a lethal second site mutation.
