WebThe Fisher-Muller hypothesis refers to: (A) the accumulation of deleterious mutations over time (B) the fact that parasites might evolve faster than their host (C) the idea that recombination accelerates evolution by natural selection (D) the fact that sex is costly (E) the fact that sexually reproducing individuals may acquire parasites. 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]. Fisher also identified a separate disadvantage to clones, which sets them apart from sexually reproducing species . In ...
WebIn evolutionary genetics, Muller's ratchet (named after Hermann Joseph Muller, by analogy with a ratchet effect) is a process through which, in the absence of recombination (especially in an asexual population ), an accumulation of irreversible deleterious mutations results. [1] [2] This happens due to the fact that in the absence of ...
