Fixation genetics
WebIn the context of population genetics, fixation is when one allele dominates another out of existence. Over time, in a gene pool, there may be two or more alleles coexisting … WebUltimately, genetic drift leads to the fixation of some alleles and the loss of others. But what about mutations that do not affect the fitness of individuals? These so-called neutral …
