Egg chambers containing homozygous follicle cell clones often fail to form a stalk on their anterior side, which results in fusion to the neighbouring egg chamber. Clones that give rise to this phenotype always include follicle cells in the anterior portion of the egg chamber, and in all cases include the anterior polar cells. Homozygous stalk cell clones do not result in a mutant phenotype.

The stalk positioned on the posterior side of the egg chamber is normal in egg chambers containing homozygous follicle cell clones, even if the clone encompasses the whole cyst.

Heterozygous ovaries show a decrease in the average number of cells in the stalk between egg chambers compared to wild type.

Mitotic clones in the dorsal wing surface covering the position of wing vein LIV differentiates a thick LIV vein. A dorsal clone between veins LII and LIII differentiates a thicker dorsal LIII and induces extra-vein differentiation in the ventral component of LIII.

Homozygous clones including dorsal and ventral clones cause extensive wing scalloping. Clones in the ventral compartment cause small nicks or loss of margin sensory elements. Clones in the dorsal compartment cause only loss of sensory elements.

Dominant by haplo-insufficiency causing notum phenotypes of evenly spaced macrochaetae. Heterozygotes have extreme extra microchaetae phenotypes.
