Homozygous clones are rarely recovered in the wing blade region of the wing disc.
Mature mutant wing discs lack the wing primordium.
The dorsal/ventral compartment boundary is only slightly disturbed in vgnull/vg83b27-R wing discs.
Homozygous clones induced in the second larval instar cause a dramatic reorganisation of cell fate in the distal wing, including the induction of epithelial folds that are reminiscent of the hinge.
Of the indirect flight muscles in vg83b27-R mutants, the dorsal medial muscles are severely reduced and the dorso-ventral muscles (lateral oblique dorsal muscles and tergosternal muscles) are minimal or completely missing (10/10 examined).
Homozygous clones in the wing disc are infrequent and round, suggesting that they sort out from surrounding wild-type cells.
Mutants exhibit a severely reduced hinge and sometimes lack both the blade and the hinge and display wing to notum transformations.
vgWR2 produces an extreme vg phenotype in combination with vg83b27-R; all adult structures derived from the wing discs, including the notum, are deleted.
Clones induced in the wing disc are readily recovered in the notum but not in the wing disc. At most two- or three-cell clones can be found in the developing wing pouch.
Wing structures eliminated, retaining only a small amount of wing hinge.
