| contents | We study the effect of the mutant's degree on the fixation probability, extinction and fixation times, in the Moran process on Erdös-Rényi and Barabási-Albert graphs. We performed stochastic simulations and use mean-field type approximations to obtain analytical formulas. We showed that the initial placement of a mutant has a significant impact on the fixation probability and extinction time, while it has no effect on the fixation time. In both types of graphs, an increase in the degree of a initial mutant results in a decreased fixation probability and a shorter time to extinction. |
