Mathematical theory of population genetics, fall 2012

Population genetics studies the genetic composition of biological populations, and its change under the influence of various factors, including natural selection, mutation, recombination and migration. Population genetics thus provides the basis for understanding the evolutionary processes that have led to the biodiversity we encounter today. 

In this course we get familiar with focal concepts and build a theoretical framework to gain proper understanding of the relevant evolutionary processes. Course will cover elementary population genetics (e.g. Hardy-Weinberg law, selection at single locus), mutation-selection models at two or more loci, equations for quantitative traits under selection and basic principles of coalescent theory.
