Insertion lines from this collection were assessed for inclusion in the Gene Disruption Project collection.
A set of X chromosome mutant stocks derived by insertional mutagenesis using the P-element construct P{lacW}; most lines have a lethal or semi-lethal phenotype. The P{lacW} construct carries a w+mC mini-white visible marker, Ecol\lacZ enhancer trap sequences, and bacterial sequences that allow plasmid rescue (FBrf0049800).
Originally isolated in line containing multiple insertions.
See: l(1)G0113G0113; not known which insertion (if any) is responsible for lethal phenotype.
