      Statement
      Reference

      Hemizygous adults show A2 segment transformation to A1, no effect on A1. Trans-combinations with lethal abd-A alleles present similar phenotypes. The embryonic phenotype of hemizygotes is like wild type. Transheterozygous combinations with other 'iab-2'-class alleles display transformation of A2 towards A1.
