Genetic mapping information
Comments

Breakpoint 1 was linked to a BamHI-BamHI restriction fragment. The position of the restriction fragment on the reference sequence was inferred by a FlyBase curator.

(Simon et al., 1991)
Comments on Cytology

Stated to be a cytologically invisible deletion.

(Roote, 1995.3.27)
