      Statement
      Reference

      sd1/sdΔB flies have rudimentary wings.

      Early-induced homozygous clones do not survive to the late third instar in the wing pouch region, but do survive in the notal region of wing discs as well as in eye discs. Late-induced homozygous clones are recovered in the late third instar in the wing pouch region.

      The eye overgrowth phenotype caused by clones expressing ykiM123.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4tub is suppressed if the clones are also homozygous for sdΔB.
