Heterozygotes have defects in the posterior alar lobe.
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 held out but also bent back at axil so appear to have a separation of 30-80o, may also be held up or down. Alulae are reduced proximally, the remnant is a triangular flap with marginal bristles. Halteres are usually partially held down, may be either up or down. A and P supra-alar and A post-alar bristles are usually missing. Lethal over 70CD deficiencies.
wing hinge Exhibits a dominant wing hinge phenotype.
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.
