A set of ~50 targeted deficiencies created by exploiting hybrid element insertion (HEI) and resolution; designed to fill gaps in deletion coverage.
28A4-28B1;28D3-28D9
Inverse PCR experiments using the Df(2L)BSC41 chromosome indicate that neither of the progenitor insertions (P{lacW}l(2)k05404k05404 and P{EP}EP946) remains in its original position, neither of the elements is intact and both insertions made jumps during the mobilisation scheme used to make Df(2L)BSC41. The proximal breakpoint is approximately 30kb proximal to the P{EP}EP946 insertion point.
The deletion chromosome retained one or both mini-white markers from the P{lacW} and P{EP}EP1090 insertions used in the screen.
