Journal of Theoretical Biology 243(2): 245-251.0022-5193http://nrs.harvard.edu/urn-3:HUL.InstRepos:4133283In this paper, we show that for evolutionary dynamics between two types that can be described by a Moran process, the conditional fixation time of either type is the same irrespective of the selective scenario. With frequency dependent selection between two strategies A and B of an evolutionary game, regardless of whether A dominates B, A and B are best replies to themselves, or A and B are best replies to each other, the conditional fixation times of a single A and a single B mutant are identical. This does not hold for Wright–Fisher models, nor when the mutants start from multiple copies.en-USevolutionary gamesfixation timefinite populationsMoran processWright–Fisher processdetailed balance conditionJournal Article2010-05-2410.1016/j.jtbi.2006.06.016
