Estimates of the historical effective population size (Ne) obtained by the software GONE for a synthetic population. The synthetic population was generated t generations ago (a and e t = 5, b and f t = 10, c and g t = 20, d and h t = 50) from the mixture of five populations which diverged T generations ago from an ancestral population. The expected Ne from the variance of the progeny number (Exp NeVk) is shown as a black dotted line. Before mixing, the expected NeVk is the sum for all populations (5000). After mixing, the expected NeVk = 100 for a–d, and 1000 for e–h. The sample size at generation zero is 100 individuals
