Df(1)BSC756 was isolated as a FLP recombinase-induced recombination event involving PBac{WH}Graff02954 and P{XP}sdd04263. The deletion was isolated as a chromosome carrying two copies of the miniwhite marker in progeny of PBac{WH}Graff02954/P{XP}sdd04263; MKRS, P{hsFLP}86E/+ females crossed to Binsinscy/Y males. These females were heat shocked as larvae as described in Parks et al., Nature Genetics 36: 288-292, 2004 (FBrf0175003). This cross and crosses in preceding and succeeding generations maintained the original genetic background of the Exelixis insertion stocks (Thibault et al., Nature Genetics 36: 283-287, 2004; FBrf0175002). The recombination event generated the genetic element P+PBac{XP3.WH3}BSC756 from the segment of PBac{WH}Graff02954 to the left of its FRT site and the segment of P{XP}sdd04263 to the right of its FRT site. The breakpoints of Df(1)BSC756 predicted from the Release 5 genomic coordinates of the transposable element insertion sites are  X:15652384 ;15708694 and the cytological breakpoints predicted from these coordinates are 13E14;13F1. Df(1)BSC756 failed to complement sd1.
