Editing Genetic drift (section)

===Other models of drift===

If the variance in the number of offspring is much greater than that given by the binomial distribution assumed by the Wright–Fisher model, then given the same overall speed of genetic drift (the variance effective population size), genetic drift is a less powerful force compared to selection.<ref name="Charlesworth09" /> Even for the same variance, if higher [[Moment (mathematics)|moments]] of the offspring number distribution exceed those of the binomial distribution then again the force of genetic drift is substantially weakened.<ref>{{cite journal | vauthors = Der R, Epstein CL, Plotkin JB | title = Generalized population models and the nature of genetic drift | journal = Theoretical Population Biology | volume = 80 | issue = 2 | pages = 80–99 | date = September 2011 | pmid = 21718713 | doi = 10.1016/j.tpb.2011.06.004 | publisher = [[Elsevier]] | bibcode = 2011TPBio..80...80D | author-link2 = Charles Epstein (mathematician) }}</ref>
