Fixation probabilities (× 106) of the coadapted haplotype A1B1 in a subdivided population (with L = 10, 20, and 50) are listed. In each set of simulations, the subpopulation size N is kept constant (at 1000) so that the total population size NT (= NL) is altered accordingly. For L = 20 and 50, scaled probabilities in units of 2s/(2NL) are also provided. (For L = 10, the scaled probabilities coincide with the absolute values × 106.) Throughout, s = 0.01, c = 0.5, and T = 100. Also listed are theoretical expectations derived from the diffusion and birth-and-death models, which should approximate high and low migration limits, respectively (see appendixes a and b).
