61% of homozygous embryos die, the remaining homozygous larvae die either as they hatch or shortly after hatching. Larvae that hatch show little or no movement and do not grow. Ovaries of females carrying homozygous germ-line clones appear normal. 21% of G-sα60A^R79/Df(2R)or-BR11 embryos die. 48% of G-sα60A^R79/Df(2R)or-BR11 embryos derived from females carrying G-sα60A^R79 homozygous germ-line clones die. G-sα60A^R79/G-sα60A^R19 embryos derived from females carrying G-sα60A^R79 homozygous germ-line clones do not have cuticle defects.
