Genetic Drift – What it is and How to Minimize its Impact on Your Research

The phenotypes of genetically modified mouse strains depend on the genetic mutation and background. Genetic background is subject to genetic drift which may result in phenotypic drift over time. In this seminar, you will learn about the following topics:

  • The basis for genetic drift
  • Case studies demonstrating genetic drift and its effects on experimental results
  • The Jackson Laboratory’s unique Genetic Stability Program to stop cumulative genetic drift
  • Steps to ensure the long-term genetic and phenotypic stability of your mutant mice

Genetics of Research Mice From Fiction to Facts

Inbred mice have historically been essential models for scientific research, and will continue to be so. Indeed, genetic standardization plays a key role in reducing variances within study populations, it facilitates both the monitoring of therapeutic efficacy, and reduces differences between studies in order to maximize reproducibility of results. 

However, recent studies have revealed that a high proportion of inbred mouse lines are genetically heterogenous populations. Genotyping inconsistencies, genetic background pollution (even if subtle), and misinterpretation of genetic testing all lead to poor mouse model genetic standardization. This presentation will review how genetic background heterogeneity may arise within a colony, and what molecular testing approaches such as polymorphic markers analysis (SNPs and STRs) really tell us about mouse genetics.
