Flies carrying dpo alleles have shortened wings and altered paths of the wing veins caused by abnormal contraction of the wing epithelia during morphogenesis. Flies carrying dpv alleles display vortex-like depressions on the notum, coinciding with the locations of certain muscle attachment sites. The orientations of the bristles surrounding the vortex are disturbed.
Homozygotes die as embryos or larvae. Homozygous clones in the wing produce discrete, round blisters of variable size. These blisters can be located anywhere on the wing. Wing venation is normal.
dpolM/dpunspecified flies have short, truncated wings, but no vortices on the thorax.
