We study two demes, and one- and two-dimensional populations. For two demes, the probability of fixation in the limit of high migration approximates that of a population with twice the size of a single deme: migration therefore greatly reduces the fixation probability. However, this behavior does not extend to a large array of demes. Then, the fixation probability depends primarily on neighborhood size (Nb), and may be appreciable even with strong selection and free gene flow (≈exp(-B·Nb) in one dimension, ≈exp(-B\\cdotNb) in two dimensions). Our results are close to those for the more tractable case of a polygenic character under disruptive selection.","lang":"eng"}],"main_file_link":[{"url":"http://www.jstor.org/stable/2409908","open_access":"0"}],"publist_id":"2735"}]
