The distribution of additive genetic variance among sites.

<p>In (A), we plot the expected contribution as a function of the scaled selection coefficient. We measure genetic variance in units of <b>v</b>_<b>S</b>—the expected contribution at sites under strong selection. In (B), we show the proportion of additive genetic variance that arises from sites with minor allele frequency (MAF) greater than the value on the <i>x</i>-axis, for different selection coefficients.
