Small clones (fewer than 150 cells) in the wing are often wild type or have a weak phenotype, even if on the dorsal surface. mew^H7 if^B2 double mutant small clones display a morphological phenotype.

Midgut does not elongate into the tubular structure but there are no obvious defects in somatic muscle morphogenesis. Dorsal herniation is not observed in homozygotes or double mutant combinations with if^k27e and if^B4. Large dorsal wing clones cause wing blisters, small clones of approximately 5 cells have no phenotype and clones of 100 cells show a mild phenotype such as wrinkles confined to one end of the clone.
