"The period before World War I led to the initiation of inbreeding in rats by Dr Helen King in about 1909 and in mice by Dr C. C. Little in 1909. The latter project led to the development of the DBA strain of mice, now widely distributed as the two major sub-strains DBA/1 and DBA/2, which were separated in 1929-1930. DBA mice were nearly lost in 1918, when the main stocks were wiped out by murine paratyphoid, and only three un-pedigreed mice remained alive. Soon after World War I, … WebMice, Inbred Strains Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations, or by parent x offspring matings carried out with certain restrictions. All animals within an inbred strain trace back to a common ancestor in the twentieth generation. Year introduced: 1972
Know Your Model: Why mouse inbred strain contribution matters
WebInbred mouse strains have important differences in their behavioral and neuroanatomical characteristics, and in their susceptibility to neurotoxic insults (Schauwecker, 2002 ). Two … WebIndividual mice within an inbred mutant strain are essentially genetically identical to each other except for the mutant gene being studied.

MGI-Guidelines for Nomenclature of Mouse and Rat Strains
WebInbred strains of mice and rats are invaluable animal resources for studying the genetic bases of phenotypic variation. They have been obtained through brothersister mating for more than 20 generations, so all individuals have the same genome (isogenic) and each individual is homozygous at each locus. What is an example of an inbred rat strain? WebInbred strains of mice are defined as strains that have been maintained by successive brother to sister matings over more than 20 generations (Green, 1975).
