Male recombination between P{lacW}GclmL0580 and P{GT1}CG45049BG02691 in trans. The regions proximal to P{lacW}GclmL0580 and distal to P{GT1}CG45049BG02691 are grossly normal, whereas the region between these two progenitor insertions has been deleted.
Inferred to overlap with: Df(3R)23D1.
Homozygotes die at the end of the third larval instar with an elongated body.
