Evolution is more than just natural selection—sometimes it happens by random chance! Genetic drift is a force of evolution that can cause some alleles to disappear from a population completely, whether or not they’re harmful. Join us to explore the impact of genetic drift on populations of different sizes!
In this activity, you will:
model the role of genetic drift on populations of different sizes;
explore extreme cases of genetic drift like founder and bottleneck effects; and
discuss different mechanisms of evolution!
