The effective founder effect in a spatially expanding population.

Evolution; international journal of organic evolution - 1 Mar 2015

Peter Benjamin M, Slatkin Montgomery

Abstract excerpt

The gradual loss of diversity and the establishment of clines in allele frequencies associated with range expansions are patterns observed in many species, including humans. These patterns can result from a series of founder events occurring as populations colonize previously unoccupied areas. We develop a model of an expanding population and, using a branching process approximation, show that spatial gradients...
