Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
female sterile (with twinry5)
At room temperature, hemizygous females show a number of egg chamber defects; 27% of egg chambers degrade between stages 3 and 10, 41% have a division defect (the egg chambers contain less than 16 germ cells), 41% fail to specify an oocyte, and 29% have defects in both germ cell number and oocyte specification. The fusome appears normal in size and extends throughout the cysts.
Allelic series: twinS1 > twinry3 ~ twinry5 > twinS3.
