The cuticle of wls^7E4 germline clone embryos that are paternally rescued show minor segmentation defects and often survive to adult stages of development. Non-paternally rescued wls^7E4 germline clone embryos show a 'lawn of denticles' phenotype. This phenotype is also seen in germline clone embryos where the mother contributes the wls^7E4 chromosome and the father contributes a Df(3L)vin5 chromosome.

Clones of wls^7E4 mutant tissue at the wing margin results in the loss of both sensory bristles and margin wing vein, but cause no other effect on wing development.
