Incorrect excision of P{UAS-ve.B} produced P{UAS-Rho.Neo.Δ}, which has a 5kb deletion removing parts of both the rho cDNA and the adjacent w+mC gene. It is predicted to encode a truncated protein containing the first 140 amino acids of rho and 10 amino acids encoded out-of-frame by the 3' end of w, which are fused to the rho coding sequence.
Most of the w ORF in P{UAS-ve.B} is deleted, leaving only a small stretch at the 3' end.
