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(2R)BSC599.
Df(2R)BSC863 heterozygotes have a Minute phenotype.
Heterozygotes have strong, unmistakable Minute phenotypes.
The presence of a deletion was confirmed cytologically, though the breakpoints were not analyzed in detail.
