Figure 6. Mismatch distributions. A, graph for Iphitime cuenoti, represents the mismatch distribution for western Mediterranean basin and Atlantic waters. Graphs for Ophryotrocha mediterranea: B, complete population from the western Mediterranean; C-D, for lineages L1 and L2, respectively. Exp, expected; Obs, observed; SSD, the sum of square deviations between the expected and the observed mismatch. TAU, Theta0 and Theta1 are the mismatch model parameters: TAU, units of mutational time; Theta0, initial population size at equilibrium; Theta1, new population size after growth or shrink.
