Figure 1
Representation of the change in genotypic frequencies from generation to generation for contrasting recombination and selfing rates. The numbers under vertical bars correspond to the genetic age of the population. The spacing separating vertical bar t and t−1 on a line was calculated as: 
where xi,t−1 refers to the expected frequency of the ith genotypic class at time t−1. Black and gray bars correspond to a population characterized with a selfing rate s=0 and s=0.5, respectively. Lines 1 and 3 and lines 2 and 4 correspond to a pair of loci characterized with a recombination rate r=0.15 and r=0.05, respectively. The sinusoidal symbol means that the spacing was truncated by the same quantity. It should be noted that this figure has only a heuristic value, as these distances are truly additive only from a given starting point in time that can be related to the Hardy–Weinberg equilibrium (t=2 for s=0) or to the approach of inbreeding equilibrium (t=4 for s=0.5). However, for s=0.5, the distance separating t=2 from t=4 is 96 and 91% as large the sum of the two intermediate intervals, for r=0.15 and 0.05, respectively.
