Polygenic Local Adaptation in Sub-Divided Populations: Effects of Linkage Disequilibria and Genetic Drift

Explore a 35-minute conference talk on polygenic local adaptation in sub-divided populations, delivered by Himani Sachdeva from the University of Vienna at the Institut Henri Poincaré. Delve into the complex dynamics of multiple genetic loci under selection, migration, and genetic drift, and their role in environmental adaptation. Examine theoretical approximations that accurately capture the effects of genetic coupling on allele frequencies at individual loci while accounting for stochastic genetic drift. Analyze hybridization in subdivided populations with multiple habitats under divergent selection. Investigate the conditions under which polygenic local adaptation can be maintained despite migration and its impact on neutral gene flow between habitats.
