Females containing homozygous germline clones have a number of oogenesis defects, with 90% of stage 14 egg chambers appearing abnormal. The major phenotypes seen at stage 14 are dumpless egg chambers (egg chambers in which the nurse cells have failed to transfer their cytoplasmic contents to the oocyte, have intact nuclei and do not appear to be undergoing programmed cell death) or egg chambers with persisting nurse cell nuclei (egg chambers in which nurse cells have transferred their cytoplasmic contents to the oocyte, but their nuclei have failed to undergo programmed cell death including nuclear condensation). In addition, some stage 14 egg chambers appear "cup-shaped" (the chorion has failed to extend around and seal the anterior end of the oocyte, resulting in an open-ended chorion phenotype). The cup-shaped egg chambers also appear to have dorsal appendage material that has not elongated properly. Some early and mid-stage mutant egg chambers contain more than 15 nurse cells and there is an excessive amount of degeneration in mid-oogenesis.

During the early stages of oogenesis, homozygous germline clones show normal subcortical and ring canal actin. However, degenerating egg chambers containing homozygous germline clones contain abnormal actin structures. In addition, 83% of the degenerating egg chambers have follicle cells which appear to degenerate at the same or a faster rate than the nurse cells. Some of the egg chambers show drastic differences in the degree of nurse cell nuclear condensation within one egg chamber. Stage 10B egg chambers containing homozygous germline clones have disorganised actin bundles which are often much thicker than normal and are not found uniformly throughout the egg chamber. Dumpless egg chambers continue to show disorganised actin structure, including small actin clumps.

Egg chambers containing homozygous germline clones show chromatin defects that increase with the age of the female. At 2 to 3 days of age, unusual nuclei with abnormal sizes and shapes are apparent. By 4 days of age, masses of DNA are visible between germline clone egg chambers. In 7 to 8 day old females, the ovaries look relatively messy and contain large masses of DNA, which appear to be the remnants of dying mid-stage egg chambers that have failed to undergo proper nurse cell chromatin condensation and engulfment. The follicle cells and cytoplasm are gone in these egg chambers.

Mutants do not show an abnormal neuronal phenotype.
