Polytene chromosomes normal.
The copia{} element is inserted 177 nucleotides 3' to the first non-coding exon of Doa and 231 nucleotides 5' to the 55kD transcript's initiating AUG.
An uncharacterised 5kb transposable element in inserted within an intron.
DoaHD heterozygous adults show significantly reduced sensitity to paraquat.
In DoaHD/Doas2784 mutants where the DoaHD allele is from the mother blackened areas are seen on the wings. When the Doas2784 allele comes from the mother the mutants die at or prior to the pupal stage.
In DoaHD/Doa5 mutants where the DoaHD allele is from the mother there is a strong transformation of females towards males, with male colouration of tergites 5 and 6, male sex combs on the prothoracic leg, and a normal but rotated female genital plate. When the Doa5 allele comes from the mother there are no survivors.
Crosses between DoaHD and Doa9 heterozygotes indicate that Doa is not an embryonic lethal, and is probably lethal during early larval stages. Rare DoaHD/Doa6 or DoaHD/Doa7 escapers of lethality are found at a frequency of approximately 0.5%. DoaHD/Doa6 escapers are more frequently female than male (ratio 4:1 ) and the male escapers are sterile despite having motile sperm.
Heterozygotes with Doa6 or Doa7 survive rarely and when they do, wa is darkened to nearly wild-type color; wsp55 reacts in the opposite manner, becoming nearly white; eyes of escapers have disarranged facets. Males of these heteroallelic combinations involving Doa6 are sterile despite having motile sperm; females and both sexes involving Doa7 are weakly fertile.

SRm160B103 strongly enhances the female to male somatic sex transformation phenotype seen in DoaHD/DoaDem mutant flies. The male genital arch and "claspers" are seen in XX individuals.
SRm160GE25979 strongly enhances the female to male somatic sex transformation phenotype seen in DoaHD/DoaDem mutant flies. The male genital arch and "claspers" are seen in XX individuals.
DoaHD/DoaDem does not suppress the lethality seen when SRm160GE25979 is expressed under the control of Scer\GAL4da.PU.
DoaHD/DoaDem almost completely suppresses the smooth, glassy eye seen when SRm160GE25979 is expressed under the control of Scer\GAL4GMR.PU. The ommatidial disruption is partially suppressed: the various cell types and layers are all identifiable albeit somewhat perturbed. Although differentiation pigment cells are observed and cone cells secrete a cornea of normal appearance, the pigment and photoreceptor cells fail to elongate to form a normal retina. There is a reduction in the levels of apoptosis (caspase activation).
One copy of DoaHD partially suppresses the lethality seen when SRm160GE25979 is expressed under the control of Scer\GAL4da.PU. The viable escapers do not display any cuticular phenotypes.
One copy of DoaHD enhances the loss of external genitalia phenotype seen in males expressing SRm160GE25979 under the control of Scer\GAL4esg.PU.
Very few animals survive when SRm160GE25979 is expressed under the control of Scer\GAL4esg.PU in a DoaHD/DoaDem mutant background, but those that do survive completely lack genitalia and analia and die shortly following eclosion.
Expression of bamScer\UAS.P\T.T:Avic\GFP under the control of either Scer\GAL4bam.T:Hsim\VP16 or Scer\GAL4vas.2.6 promotes the differentiation of spermatogonia to spermatocytes in DoaDem/DoaHD testes.
DoaHD Ef1γGE29510/DoaDem flies show a number of defects, including ectopic wing venation, failure of either of the crossveins to attach (particularly the posterior crossvein in males), aberrantly formed crossveins, occasional eye roughness, curved wings and rarely, partial rotation of the female genitalia.
DoaHD in combination with E(gl)3Cunspecified results in flies with normal eyes, wings and bristles. No suppression of wa is seen in these flies.
Rare DoaHD/Doa6 or DoaHD/Doa7 escapers show extreme suppression of the wa phenotype, such that eyes, Malpighian tubules, ocelli and testes are essentially wild-type in colour. They have disordered eye facets and scutellar bristles are often missing or abnormal. Male escapers carrying wsp55 have bleach-white eyes.

The "HD1" and "HD2" alleles have an insertion in an identical location. They both potentially originate from a single event during mass crosses.
