Example graphical representation of a demographic scenario with population splits, migration, and growth. f is the size of a population in units of 2N, β = 2Nb is the growth rate. Above the dotted arrows are the backwards migration rates, again scaled in units of 2N. Scheme code implementing the complete model is shown in Figure 5.
