How Selection Changes the Genetic Composition of Population - Principles of Evolution, Ecology and Behavior

Explore the fundamental principles of genetics and evolution in this 50-minute lecture from Yale University's "Principles of Evolution, Ecology and Behavior" course. Delve into the history of genetics, different genetic systems, and the mathematical foundations of genetic change. Learn how selection alters the genetic composition of populations, comparing the rates of change in various genetic types. Discover why adaptive genetic change follows a specific pattern and understand the factors influencing the speed of evolution in sexual diploids, asexual haploids, and other genetic systems. Gain insights into how gene frequencies shift in large populations under selective pressures, providing a comprehensive overview of the intricate relationship between genetics and evolutionary processes.
