Fixation probability

WebApr 11, 2016 · Introduction In a panmictic population, the probability of fixation of an allele at a neutral locus is equal to its frequency at that time. I will refer to this probability of … WebIn particular, the fixation probability of a new mutation present in a single copy is 1/ N. It is straightforward to extend the WF model to diploid systems by exchanging N →2 N, as well as to nonconstant population sizes by taking larger or smaller samples in each generation.

WebThe graph illustrates that the fixation probability is much greater when the population size is small. We see that if the population size is 50, there is a 60% fixation; on the other hand, if the population size is 500, there is a 10% chance of fixation. 5.
