Exhibits a dominant wing hinge phenotype. The nervous system in homozygous embryos appears wild-type.
Lethal when heterozygous with Dr72 or Dr513. The wing phenotype of the dominant alleles is due to ectopic expression of D in the anlage of the hinge in the wing imaginal disc, as can be reproduced using a DScer\UAS.cSa driven by Scer\GAL430A or Scer\GAL4zfh2-MS209.
Wings are held out at 30o with a slight kink at the axil. Alulae are slightly reduced, both in length and width relative to TM3, which itself has alulae slightly reduced relative to wild type. Halteres are generally in a normal position, presutral bristles are sometimes missing. D phenotype is weak and variable, can overlap wild type especially in young flies. Chromosome also exhibits a dominant kni-like phenotype. Lethal over 70CD deficiencies.
A.T.C. Carpenter.
Shows tissue specific loss of D expression in the embryo.
Shows tissue-specific loss of D expression thus is a regulatory mutation.
Associated with a recessive lethal phenotype that maps to 70D1-2.
