The Expression of Variation - Reaction Norms - Lecture 8

Explore the concept of reaction norms in this 43-minute lecture from Yale University's "Principles of Evolution, Ecology and Behavior" course. Delve into how a single genotype can produce a range of phenotypes depending on environmental factors, while considering phylogenetic constraints. Examine how reaction norms vary within populations and investigate the developmental constraints that influence them. Learn about the benefits and limitations of studying reaction norms to gain a deeper understanding of phenotypic plasticity and its role in evolution and ecology. The lecture covers introduction to reaction norms, their presence in populations, developmental constraints, and the advantages and drawbacks of reaction norm studies.
