Imprecise excision of the progenitor insertion, resulting in a 757bp deletion containing most of the first exon and part of the first intron (nucleotides corresponding to -472 to +118 relative to the transcription start site are deleted).
757bp deletion resulting from the imprecise excision of P{EP}EDTPEP922, removes sequences from -472 to +118 relative to the EDTP transcription start site (deletion extent from reported sequence).
Ovaries are smaller than normal in females containing homozygous germline clones. Egg chambers from stage 1 to 4 are seen, but later stages are not observed.
