Simulating Random Events in Evolution: Genetic Drift, Founder

If allele frequencies change from generation to generation, then evolution has occurred. The purpose of this simulation is to ...

Genetic drift

On one hand, high migration rates integrate populations into larger units, which tend to retain genetic variation just because of their size. On the other hand, movement of individuals ...
