The size of some DO1 muscles, particularly in the sixth row of somatic muscles, is reduced in mutant embryos and the space between the DO1 and DO2 muscles is expanded compared to wild type.
The genital disc is severely reduced in dppd12/dppd14 larvae.
Heterozygotes of dppd12 and dppd14 have the distal leg structures missing.
medulla neuropil ommatidia In dppd12/dppd14 flies the medulla neuropil is reduced to a size similar to that produced by inactivating wg prior to 44hr AEL. The number of ommatidia is correspondingly reduced.
dppd6/dppd14 clones are associated with defects in the wing, but not the notum. dppd6/dppd14 clones in the posterior compartment are associated with normal venation.
In dppd12/dppd14 heterozygotes all imaginal discs are extremely reduced, die as early pupae. Imaginal disc transplantation demonstrates that only the anterior notum and most of the proximal anterior wing margin are produced. Wing discs do not have regenerative capacities.
