Estimates of the historical effective population size (Ne) obtained by the software GONE for a population subdivided into two subpopulations. The n = 2 subpopulations of size N = 1000 individuals each have continuous reciprocal migration at a rate m per generation (a Nm = 1 migrant each generation, b Nm = 2 migrants each generation, c Nm = 5 migrants each generation, d Nm = 10 migrants each generation, e Nm = 20 migrants each generation, f Nm = 1 = 10 migrants each 10 generations). The two black dotted lines show the expected NeVk of one subpopulation (lower line) or both together (upper line). The red lines correspond to estimates obtained from 100 individuals sampled at generation zero from the two subpopulations (half of each), whereas the blue lines correspond to estimates obtained from 100 individuals sampled from a single subpopulation
