Explore the complex dynamics of migration in population genetics through this 28-minute lecture that examines how population movement affects genetic diversity and fitness. Learn about homogenization processes that occur when populations exchange genetic material, understand genetic rescue mechanisms that can save small populations from extinction, and discover how outbreeding depression can negatively impact hybrid offspring. Analyze real-world examples and interactions that demonstrate these migration effects, gaining insight into the delicate balance between beneficial gene flow and potential genetic disruption in natural populations.
