Generations to fixation = 2 ln(N) / s
Probability of fixation = 2s
Are there domains limits for ‘s’ on those equations?
It seems to me that if you have an s that is negative, you get a nonsensical answer for both equations. Though I suppose that equation one’s answer can be interpreted to mean that it would take -[Generations to fixation] generations for a bad, but ubiquitous mutation to get winnowed down to one individual.
But with the second equation, a negative s leads to a less than zero chance of fixation and an s higher than 50% leads to a greater than 100% chance of fixation.
