The entire gene region is deleted.
Scer\FRT-mediated recombination between the two progenitor insertions has resulted in the deletion of the genomic sequence between them.
Each denticle row is present and the overall morphology of the denticles is unaffected, but denticles show a marked decrease in size.
nyoΔ33 has denticle phenotype, non-enhanceable by Df(3R)neoΔ32/Df(3R)meyΔ13
nyoΔ33, Df(3R)neoΔ32, Df(3R)meyΔ13 triple mutants show denticle defects similar to each single mutant.
