The Rat Strain Ontology (RS) is currently being developed at the Rat Genome Database. For more information about this vocabulary or to request additions or changes, please contact us (http://rgd.mcw.edu/contact/index.shtml).
Inbred Strains are produced by brother x sister mating for 20 or more consecutive generations, and individuals of the strain can be traced to a single ancestral pair at the 20th or subsequent generation.
