Recombination between the two progenitor insertions has resulted in deletion of 158kb of sequence between them. The deletion was confirmed by PCR amplification.
Deletion of about 158kb downstream of vvl, resulting from FLP-catalyzed recombination using the FRT-containing transposons PBac{WH}f07247 and PBac{WH}Mis12f03756. At least 10 genes are removed.
Embryos homozygous for Df(3L)vvl7247-Mis12 do not display any tracheal defects.
