Bacteria grown in complete medium and in the presence of proflavin are plated on complete medium and then replica-plated onto medium lacking tryptophan to identify Trp auxotrophs. Lys auxotrophic bacteria grown in minimal medium + Lysine and in the presence of ENU mutagen are then plated on minimal medium so that only Lys* revertants can form colonies. Fruit flies are normally killed by high doses of the drug neomycin. Progeny whose male parents were exposed to X-rays are grown on food containing • neomycin so that only neomycin-resistant mutants will live.
