A set of ~800 largely isogenic deficiency stocks created by FLP-induced recombination between FRT-carrying transgenic insertions; molecularly defined deletion endpoints correspond to initial location of the progenitor insertions. Designed to fill gaps in deletion coverage and breakpoint placement; also used to replace older available deficiencies that have not been molecularly mapped.
Breakpoint from FlyBase's release 5 sequence location of progenitor insertion.
The cytological breakpoints of Df(1)BSC763 predicted from the Release 5 genomic coordinates of the progenitor PBac{WH}f01416 and P{XP}CHES-1-liked01890 transposable element insertion sites are 7B2;7B6.
