Polytene chromosomes normal.
The wings of Doa7/Doa9 mutant flies exhibit a held-out phenotype.
In Doa7/Doa9 mutants where the Doa7 allele is from the mother it is predominantly males that are observed. These have rough eyes, held-out and fragile wings, duplication of the postalar bristles, missing scutellar or ocellar bristles, slight sexual transformations of females and disorganisation of the vaginal bristles. When the Doa9 allele comes from the mother there are no survivors.
Homozygous mutant clones are not detected in the eye when somatic recombination is induced in 5 to 6 day old larvae. Mosaic eye containing wild-type twinspots are rough. Disruptions in the ommatidial pattern are seen near homozygous wild-type clones. Occasional anterior wing margin bristles are also missing when clones are induced in 4 to 6 day old larvae.
