Substitution rates and genetic diversity.

<p>(a) Estimates of relative substitution rates (<i>μ_R</i>) and their 95% higest posterior densities based on the analyses of eight taxa in *beast; loci are ranked on the x-axis (lowest to highest) by values of nucleotide diversity within gadwalls, and the horizontal dashed line indicates the mean relative rate (1.0 by definition). (b) Relationship between <i>μ_R</i> and nucleotide diversity within gadwalls.
