Abstract
Genetic drift is an important mechanism in microevolution, but it can be more challenging to understand than other mechanisms (e.g., natural selection). This group project allows students to simulate random changes in allelic frequencies over generational time using a few simple supplies and was well received when included in an introductory biology course at the collegiate level.
