Describes an experimental cross in mice that can be used to define and map induced germ-line mutations that map to a single chromosome. The cross is a modification and extension of a conventional three-generation recessive mutagenesis screen. Includes: The Mutagenesis Breeding Plan; Consomic Strains; Generating Mutations; Generating and Genotyping G2 Females; Genotyping G3 Progeny; Phenotyping G4 Progeny; etc.. - [Read A Targeted Screen to Detect Recessive Mutations that have Quantitative Effects Protocol]
