Glossary Term Congenic Strain
Definition An inbred strain of mouse that contains a small genetic region (ideally a single gene) from another strain, but which is otherwise identical to the original inbred strain. Congenic strains are derived by backcrossing to a parental inbred strain for at least ten generations while selecting for heterozygosity at a particular locus. A.BY-H2b H2-T18b/SnJ is a congenic strain.
