Figure.9.2a Response to selection in a set of 25 replicate populations, showing the effect of effective population size. In the animations depicted here, lineages of moderate size respond to very slight directional selection (s=0.01) for 400 generations. The trajectories of the lineage means (shown in black) reflect both response to selection and drift. The deterministic response to selection is shown as a white line. The 99% confidence limits for the overall lineage mean are shown with purple lines.

held constant at 500 and additive genetic variance is varied.
