Caption: Equilibrium of mutation and selection processes: A population can be divided into groups of individuals that carry different numbers of deleterious mutations. Groups with few mutations are amplified by selection but lose members to other groups by mutation. Groups with many mutations don't reproduce as much, but gain members by mutation.
