More than 50% of homozygous larvae survive the pupal stage to eclosion. Homozygous ovaries from third instar larvae have an overproliferated germline. By the adult stage, 89% of homozygous females have "differentiated ovaries" (containing recognisable egg chambers and/or germline cells in at least one ovariole) and 11% of females have one germlineless and one differentiated ovary. Developing mutant egg chambers sometimes contain few nurse cells but no oocytes. The number of ring canals is reduced in these egg chambers and there is a pronounced unequal ploidy among the nurse cells. Somatic defects are also detected at a low frequency, such as long interfollicular stalks and the disruption of single-stack cells in the terminal filament.
Small ovary phenotype.
