Inbreeding is a powerful method to reduce heterozygosity at every locus of the mouse genome, but genetic drift can and does occur, which can confound reproducibility of research.

- What genetic drift is, why it impacts study results, and how quickly it can develop
- Why genetic drift is more common in smaller colonies than larger ones
- Published examples of where heritable phenotypic differences between substrains have arisen
- How to limit genetic drift while promoting reproducibility and responsible animal use
