Member of large scale dataset(s)
Dfs_BSC_set2

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.

Comments on Cytology

Exelixis, Inc. determined the insertion site of P{XP}d10323 to be at Release 3 genomic coordinate 2843728 on chromosome arm 2R. This corresponds to 43E16 on the Release 3 and 4 genome maps. The predicted position of PBac{WH}CG8728f01392 on the Release 4 map is

(Christensen and Cook, 2007.3.22)

43F4. Consequently, the cytological breakpoints of Df(2R)BSC265 are

(Christensen and Cook, 2007.3.22)

predicted to be 43E16;43F4.
