  1. The calculated equilibria percentages (see Equation 3) for X-bases in X-rich MRI and control regions with average X-composition. Projected equilibria are given based on the substitution rates of rare, minor, medium, and major SNPs as well as for the fixed substitution rates (chimp-macaque to human).
