This page provides access to searchable, hypertext listings of inbred strains of mice and inbred strains of rats. Both sets of information were provided by Dr. Michael FW Festing (MRC Toxicology Unit) and were converted for Web presentation by the Mouse Genome Informatics Group at The Jackson Laboratory.

There are several points of entry to these listings:

• Introduction to the mouse listing.
• Introduction to the rat listing.
  
  
• Index of major mouse strains.
• Index of major rat strains.
  
  
• List of mouse references, cross-referenced to strains.
• List of rat references, cross-referenced to strains.
