Homozygous females retain mature eggs. The phenotype is only partially penetrant at lower temperatures than 29oC.
females produce few if any eggs. temperature-sensitive. Adults normal in appearance. Females retain eggs but are partially fertile at 16oC. Mosaic results at 29oC indicate mutant interferes with somatic function of normal allele.
Germ line clonal analysis at 29oC shows that fs(1)A1001 function is required in the soma.
