    Detailed Description
    Statement
    Reference

    sav1/sav3 animals and sav1/Df(3R)EB6 animals have a hatching rate of 85.5% and 83.3% respectively. 90-95% of animals of these genotypes fail to grow and die as first instar larvae. Mosaic flies with eyes containing clones homozygous for sav1 (clones generated using the "eyFLP" system) have eyes with an increased representation of mutant tissue over wild-type tissue. In mutant clones in the adult retina, almost all the ommatidia contain the normal complement of eight photoreceptor cells. However there is increased spacing between adjacent ommatidia - there are many additional interommatidial cells.

    sav1 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).
