WebMar 10, 2016 · Theory has proposed several distinct population genetic mechanisms that could underlie this advantage. For example, sex can promote the fixation of beneficial mutations either by alleviating interference competition (the Fisher-Muller effect) or by separating them from deleterious load (the ruby in the rubbish effect). WebOct 1, 1998 · A model of positive selection developed by Fisher ( 1930) and Muller ( 1932; see also Maynard Smith 1988) proposes that adaptation is more rapid in a large finite population of sexual organisms than in an equally large, but asexual, population evolving in the same environment.

WebMar 15, 2024 · Hill–Robertson interference may involve new beneficial mutations, as in the Fisher–Muller theory, new deleterious mutations, as in Muller's Ratchet, or both, as in the Ruby-in-the-rubbish hypothesis (Peck, 1994). Although mutation was symmetrical, the generation of selective interference in the model was due to new beneficial mutations.
