<p>Fixation probabilities, , of various graphs under mixed -updating for <i>N</i> = 7 in neutral evolution.</p>

For each graph depicted, the small star symbol on the differently shaded vertex indicates the initial mutant location. <b>a, i)</b> A star graph with the initial mutant location at the center. Relative to under the unbiased process, Bd-biased processes have a lower but dB-biased processes have a higher . <b>a, ii)</b> A star graph with the initial mutant location at a leaf.

Relative to under the unbiased process, Bd-biased processes have a higher but dB-biased processes have a lower . <b>a, iii)</b> A graph composed of a star and two additional edges. Relative to under the unbiased process, both pure Bd and pure dB processes have a lower . However, panel <b>b, iv)</b> shows that the graph from <b>a, iii)</b> has higher than the unbiased process when is slightly smaller than 1/2.
