“Tubby” strain: c57BL/6JEi tub.

A naturally occurring mutant whose genetics have been studied and are fully reproducible. They are not a product of genetic engineering any more than different breeds of dog or cat. The Jackson lab breeds mice for the traits it wants, and these varieties were discovered as mutants in naturally occurring litters of mice.

The Jackson Laboratory breeds genetically specific mice and ships over two million mice per year to medical research laboratories around the world. This enables scientists in different parts of the world to test and duplicate experiments on genetically identical specimens. The mice are bred for naturally occurring mutations that mimic human maladies. Mice are the best genetic model for medical studies because they are so well known genetically, even better than humans.
