Shows a multiple wing hair phenotype.
If somatic clones are induced earlier than second instar larvae, no clones survive to adulthood. If induced during the third instar many clones are seen, none larger than 10 cells in size. When clones are seen in the wing blade, a number of different phenotypes are seen in wing hairs. Hairs can be longer than normal. Hairs are often split distally, if this happens they are pointed 30 to 60o apart from one another and are usually approximately normal in length, though some can be significantly longer than normal. Some clones produce four to six wing hairs, of often variable length, in a single cell - the wing is frequently kinked in the region of such cells. Occasionally cells are seen that produce more than a dozen relatively normal-sized hairs. Somatic clones in the wing also leads to splitting of bristles in the wing margin is also seen, these bristles are also larger than normal. There is no evidence of socket cells surrounding these "bristles". Somatic clones in the pupal wing have larger cells with larger nuclei than wild-type that may be polyploid. Also prehairs are formed over a large region of the cell in these clones, unlike wild-type where they are restricted to the distal most part of the cell. Reducing the cell size in wings with mutant somatic clones by starvation produced a partial suppression of the phenotypes seen.
