wild-type allele
One copy of the 2.9kb duplicated segment is lost and a 5' truncated 3542bp F-element (Fw element) is acquired.
Insertion of a 3.4 kb F-element at map position +0.8 relative to the transcription start site of w.
Moderately repetitive DNA from outside the w locus (which is present at approximately 50 sites in the genome) has inserted into the wi lesion with the concomitant loss of the wi duplication.
Eye colour: wild-type.
Revertant.
