Homozygous clones can be recovered in the eye. Females containing homozygous germ-line clones show defects in early oogenesis. Very few clones are produced, several have wild-type morphology, one as late as stage 10, one clone arrested at stage 6 and a clone that degenerated at stage 8.
Selected as: a mutation that results in a failure to produce eggs when females carry homozygous germ-line clones.
