gypsy element insertion.
Females produce 'appendageless' eggs.
In stage 13 of oogenesis nurse cell domain distension fails and subsequent readsorption of nurse cells produces a typical appendageless egg. Chorion gene amplification is abnormally arrested in stage 13 and 14 brnpr-fs follicles. Mosaic experiments reveal a somatic but not germ line requirement for 'npr' function.
Mature follicles of homozygous females have minor defects in the endochorion (which are uniformly distributed) and have defective respiratory appendages.
Morphologically abnormal eggs that fail to hatch. Various defects in respiratory appendages and chorionic architecture.
Germ line clonal analysis shows that fs(1)de1f is soma-dependent.
