Features of inbred mice. A strength of the laboratory mouse as a model system results from the availability of hundreds of inbred strains which harbor different characteristics, including some that are prone to develop specific types of cancers.
The laboratory mouse originated from a mixture of M. m. domesticus, M. m. musculus, and M. m. molossius subspecies. An inbred strain of the laboratory mouse is defined as a strain that has been brother/sister mated for 20 or more consecutive generations and can be traced to a single ancestral pair.
