text: 'We investigate the probability of fixation of a chromosome rearrangement
in a subdivided population, concentrating on the limit where migration is so large
relative to selection (m ≫ s) that the population can be thought of as being continuously
distributed. 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.'
