Homozygous clones can be recovered in the eye. Females containing homozygous germ-line clones show defects in early oogenesis.
Selected as: a mutation that results in a failure to produce eggs when females carry homozygous germ-line clones. It is not certain whether the lethal mutation and the sterility map to the same lesion, since only a single allele of this complementation group has been recovered.
