Model analysis. (a) Fit for concurrent displacement model. The plot shows the relationship between the apparent mean displacement time versus the mismatch position in the invader (blue) and the incumbent (orange). We used five fitting parameters, the annealing rate (k_a), the dissociation rate constant (k₀), the branch migration rate (f), the stability factor (s), and the mismatch migration ratio (a). The points included in the fitting routine are marked by ×. (Dashed lines) Fit by our model; (dotted lines) 95% confidence intervals at the input values. (b) Splitting probability distribution. The bar graphs show the splitting probability versus state number with the mismatch position varying from 1 to 7 (top to bottom, left), and from 8 to 14 (top to bottom, right). The parameters obtained from the fit in (a) were used to calculate the probabilities. (Red vertical dash) Mismatch position. To see this figure in color, go online.
