WebNational Center for Biotechnology Information WebSep 2, 2010 · An unselected, non-inbred population of laboratory mice has been propagated for 25 generations by 20 pairs (families) of mice, each leaving one son and one daughter selected at random from the litter. The daughter was given the family number of her dam, while her mate came from another family varying systematically in different generations.

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, …
