Homozygous caupDFM1 somatic clones (containing the alleles caupDFM1 and araDFM1) in the abdomen are normal, except for lateral ones. The clones found in the lateral domains of the tergite are often depigmented; usually not all parts of the clones are affected to the same extent. These clones tend to be roundish.
Homozygous Df(3L)iro-DFM1 (containing araDFM1 and removing caup) clones cause a series of phenotypes, adding progressively more 'ventral-type' tissue in the following order: dorsal eye overgrowth or ectopic dorsal eyes, overgrowth of ventral type of cuticle (ptilinum and rostral membrane) ectopic antennal pouches, antenna and maxillary palps. The extra head structures are produced autonomously, but the eyes can be composed of both mutant and wild-type ommatidia. The ectopic ventral structures, all grow from the orbital region of the head. The rest of the dorsal head is displaced by the over-grown tissue.
