Weak selection in evolutionary game

The conditional fixation time can be longer on average for a weakly selected mutation (positively) than a neutral mutation. (Martin Novak comment: this might be because we are calculating the “conditional fixation time”. In such cases, most of the neutral mutations don’t make it to fixation. Those that do make it have a certain average time between arise and fixation. For weakly selected mutations, the effect of selection is weak and therefore the difference in time is not large. However, when mutations are weakly selected, they are more likely to go to fixation, however also hang around for a longer time.)
