Venue: Room 316 of Environment Building, Renmin University

Abstract： Population genetics is concerned with the study of the genetic composition of biological populations and how this composition is shaped by ecological and genetic factors such as selection, mutation, recombination, or migration. Therefore, the evolution of the genetic composition of populations subject to these mechanisms is investigated using mathematical models. This talk will focus on ODE and PDE models of spatially distributed populations dispersing in heterogeneous environments. We will review both classical and recent results about the interaction of selection and migration when only a single gene locus is under selection. Finally, we will briefly present recent results and open problems for the case when selection acts on more than one gene locus and recombination needs to be taken into account.
