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.
Inferred to overlap with: Df(3L)BSC395.
The breakpoints of Df(3L)BSC840 predicted from the Release 5 genomic coordinates of the insertion sites of the progenitor transposable elements PBac{RB}CG11570e01503 and P{XP}d09934 are 3L:11949919 ;12104338 and the cytological breakpoints predicted from these coordinates are 68E3;68F3.
