      Statement
      Reference

      E(z)son1 strongly suppresses the trx-like phenotype (transformation of T1 to T2, T3 to T2 and A5 to A4) seen in E(z)Trm heterozygotes; phenotype is nearly wild-type.

      (Bajusz et al., 2001)

      Lethal in trans to E(z) null alleles or deficiencies.

      Statement
      Reference

      Strong suppressor of the z-w interaction. E(z)son1/+ shows 11% suppression of the nos abdominal phenotype. E(z)son1/E(z)son3 shows 100% suppression of the nos abdominal phenotype, when the E(z)son3 allele is contributed from a germ line clone.
