Two situations where f is affected by deviations from the model. (A) The effect of a change in N e on the value of f. This change in N e occurs in the most recent common ancestor of the four simulated sequences. Population ratio refers to its N e after versus before this change. (B) The effect of an increased C to T substitution rate. Categories A, B, and C are defined in Table 1.
