Relationship between the parameters of fixation. A) The time at which mutations initially occur (τup) negatively correlates with the initial rate of increase, Sup (P = 0.0026, Spearman’s rank correlation). B) Mutations with lower initial rate of increase (Sup) take more time to fix (P = 0.0016, Spearman’s rank correlation). C) Late-occurring mutations (larger τup) take more time to fix (P = 0.0092, Spearman’s rank correlation). D) No correlation found between the selective advantage measured by direct competition experiments (wmut – 1) and the initial rate of increase (P = 0.3678 Spearman’s rank correlation). For all panels, double asterisks denote significance at P < 0.01 and ‘NS’ conveys non-significance (P > 0.05).
