ing from the example, suppose that there are n subpopulations that have reached equilibrium sizes N1, . . . Nn and let mij be the probability that an individual in subpopulation i is a descendant of an individual in subpopulation j. That is, to build up subpopulation i in generation t + 1, we sample Ni times with replacement from generation t, picking at random from subpopulation j with probability mij . Note that with the definition of the coalescent in mind, these are the backward migration… CONTINUE READING
