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}d05552 to be at Release 3 genomic coordinate 10314218 on chromosome arm 2L, which is predicted to lie in 31D7 on both the Release 3 and Release 4 maps. PBac{WH}pief05500 is predicted to lie in 31D11 on the Release 4 map. Consequently, the cytological breakpoints of Df(2L)BSC209 are

(Christensen and Cook, 2006.8.30)

predicted to be 31D7;31E1.
