Homozygous females are sterile, and lay fewer than 1% as many eggs as wild-type. The endochorion has occasional defects, and the respiratory appendages are essentially normal.
Homozygous females lay few or no eggs. Mature follicles of homozygous females have major defects in the endochorion (which are uniformly distributed) but the respiratory appendages are normal.
Oviposition of few if any eggs. Various defects in respiratory appendages and chorionic architecture of hand dissected eggs.
double mutant?
Germ line clonal analysis shows that fs(1)ne3a is germ line-dependent.
Recombination mapping of fs(1)ne3a is not consistent with the phenotype being caused by a single mutation. The phenotype of the fs(1)ne3a chromosome may be caused by two mutations, one at an extreme distal position and one at an extreme proximal position on the chromosome, both of which must be present to confer the "no egg" phenotype. Since two alleles of fs(1)ne3 have been isolated in the same screen, this suggests that at least one mutation was present on the parental chromosome. Germ line clonal analysis shows that fs(1)ne3a is germ line-dependent.
