Standard deviations are shown in parentheses. The model used to produce Figure 4 was simulated. Random samples of size 20 were generated at three time points (indicated with black, red and blue arrows in Figure 4a). The statistics were calculated using sequence variability at two types of neutral sites—those in the two flanking regions (Flanking) and those embedded in the centrally located selected region (Embedded).
