91% of Df(2R)enΔ530/Df(2R)en-SFX31 wings exhibit split veins in the posterior compartment.
Inferred to overlap with: Df(2R)en-SFX31.
Homozygotes have a defect in the posterior compartment of the wing: there is a split in the wing vein at the intersection of the anterior crossvein with the IV longitudinal vein, and the intersection of the longitudinal vein with the wing margin. 93% of mutants show this phenotype.
