Isogenic strains (inbred strains and F1 hybrids) are like immortal clones of genetically identical individuals. The same genotype can be reproduced indefinitely. They have already made a substantial contribution to biomedical research.
Information on the history, effects of inbreeding, properties, nomenclature and breeding of isogenic strains and the reasons why their use increases statistical power is given in this section.
A table of the characteristics of individual strains of mice and rats is maintained on the Jackson Laboratory web site (see mouse strains and rat strains).
