FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
Oogenesis is blocked at stage 8-9 in homozygous females. Follicle cells continue to differentiate, resulting in very small, cup-like eggs. Heterozygous females produce bicaudal embryos at a low frequency, the incidence being highest at 25oC.
