The Importance of Genetic Background in Mouse Models

WebInbred mouse strains are defined as colonies produced by a minimum of 20 generations of brother-sister mating, traceable to a single founding pair. This mating structure results in animals that are genetically identical within each inbred strain (i.e., fundamentally free of genetic variants that could increase variation in experimental results).
