Table 1 Comparison of concepts covered by the two lab activities and the GeDI
Concept | Covered by faculty-developed activity | Covered by SimBio “Genetic Drift and Bottlenecked Ferrets” | Covered by GeDI |
|---|---|---|---|
Genetic drift is random sampling error that occurs in every generation | No | Yes | Yes |
Genetic drift causes loss of genetic variation within populations and hence increases differentiation between populations | Yes | Yes | Yes |
Relationship between population size and strength of genetic drift | Yes | Yes | Yes |
Effects of genetic drift can overwhelm effects of natural selection in small populations | No | Yes | Yes |
Effect of population bottleneck on genetic drift | Yes | Yes | Yes |
Definition of metapopulation | Yes | No | No |
Computation of F statistics | Yes | No | No |
Interpretation of F statistics | Yes | No | No |
