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.
Df(2R)BSC273 heterozygotes show an apparently normal temperature preference profile and an apparently normal circadian behavior (i.e. proportion of rhythmicity and circadian period), as compared to wild-type controls.
Dominantly modifies the size of pupae relative to wild-type controls.
