P element inserted at 5' end of the dx transcription unit.
dxP mutant larvae have normal wild-type numbers of crystal cells.
Homozygous females have an excess of microchaetae, having 143.00 +/- 1.92 thoracic microchaetae per heminotum (compared to the wild-type number of 130.35 +/- 1.54).
Viable. Extra wing vein material at tips. Weak rough eye phenotype: irregular ommatidia, bristles are duplicated or missing. No visual abnormality.
Weak dx allele.
Seven Δ2-3 induced wild type revertants have lost the P element.
