Chapter 1 Effect of stabilizing selection on trait distribution


Figure 1.6 This animation shows the effects of differing intensities of stabilizing and disruptive selection on a hypothetical trait distribution. The trait distribution before selection is shown in blue and after selection in black. The trait distribution is a normal curve (both before and after selection) with variances P and P* before and after selection, respectively. The trait variance of the distribution is affected by selection, but the mean is not.
