      Exhibits the Ubx effect: heterozygotes partially transform the capitellum of the haltere into the wing blade.

      (Chen et al., 1993)

      Homozygous and hemizygous viable. The capitellum of the haltere shows a partial transformation to wing blade in heterozygotes. Enhances the bristle duplication phenotype of Dl7 heterozygotes.

      (Mortin et al., 1988)

      Homozygous and hemizygous viable. Exhibits slight enhancement of Ubx when heterozygous to + but not in heteroallelic combination with any of the interacting mutant alleles; it decreases the enhancing effects of RpII215Ubl. Increases the number of duplicated bristles of Dl/+ in all genotypes. viable
