Fisher-muller hypothesis
WebAug 21, 2013 · Muller independently stated the same idea, and it is now known as the Fisher-Muller hypothesis. It requires mutations of small effect, large populations and high mutation rates for sex to acquire its advantage [14, 15].

It stats that recombination creates novel genotypes that can resist infection by parasites (Lively, 2010). The Red Queen Hypothesis brings together two evolutionary theories. The key part of this theory includes the evolutionary arms race, which is the idea that predators and ...
