Homozygous clones induced in the eye occupy most of the eye and cause overgrowth.
exNY1 is a recessive, cell-autonomous mutation that allows recovery of Df(1)su(s)R194/+ clones in the adult eye in animals with mosaic eyes containing two genotypes of cells with respect to RpL36; cells which are Df(1)su(s)R194/+ and cells in which the haplo-insufficiency of Df(1)su(s)R194/+ for RpL36 has been rescued by RpL36+t4 (in a wild-type background the Df(1)su(s)R194/+ clones are eliminated by cell competition and are not seen in the adult eye in these animals). Mosaic wing discs contain a similar number of apoptotic cells compared to control discs. The apoptotic cells are predominantly of the Df(1)su(s)R194/+ ; exNY1 genotype and adjacent to the clone boundary.
Df(1)su(s)R194/+ ; exNY1 Mad10 clones are recovered in adult eyes, although they are smaller than Df(1)su(s)R194/+ ; exNY1 clones.
Selected as: A mutation that allows survival of cells being competed due to haplo-insufficiency for RpL36.
