The wing area of homozygous flies is significantly smaller than that of controls, with the wings being specifically shortened in the proximal-distal axis. The mutant flies sometimes show shortening of the legs, usually restricted to the T3 leg; leg segments (primarily the femur and tibia) are shortened and abnormally bent.
Drakdel/DrakKO adults show a reduction in wing area compared to controls and a partially penetrant phenotype of T3 leg defects.
Drakdel/DrakKO, rok[+]/Rok2 has lethal phenotype, suppressible by sqhE20.E21
DrakKO has visible phenotype, suppressible by sqhE20.E21

Drakdel/DrakKO, rok[+]/Rok2 has wing pouch phenotype
The shortening of the wing which is seen in DrakKO flies is enhanced if the flies are also heterozygous for one of Rho172O, zip2 or Sb63b.
The wing discs of Drakdel rok2/DrakKO third instar larvae are composed of unusually thin epithelial layers which are grossly distorted. The wing pouch region has folds which project basally out of the plane of the epithelium, and these distortions are accompanied by massive apoptosis.
The T3 leg defects seen in DrakKO mutants are suppressed by flwG0172.
Expression of sqhE20.E21 suppresses the short wing and deformed T3 leg phenotypes of DrakKO mutants. Expression of sqhA20.A21.T:Zzzz\FLAG has no effect on the deformed T3 leg phenotype of DrakKO mutants.
