Modeling Polygenic Barriers to Gene Flow Between Species

Explore the complexities of polygenic barriers to gene flow between species in this lecture by Himani Sachdeva. Delve into theoretical models and empirical approaches used to understand how multiple genetic loci contribute to reproductive isolation and speciation. Learn about the challenges of integrating polygenic adaptation into evolutionary biology frameworks, moving beyond traditional views of adaptation occurring through either large changes at few loci or infinitesimal changes at many loci. Gain insights into quantitative methods for describing various adaptive scenarios and their relationship to empirical data. This talk is part of a broader program on theoretical and empirical approaches to polygenic adaptation, featuring pedagogical lectures, research seminars, and interactive discussions aimed at advancing our understanding of complex phenotypic traits and their genetic underpinnings.
