Web basically, in organisms with high mutations rates (such as rna viruses), muller's ratchet suggests that the mean fitness in a population will always decrease. Web muller's ratchet 1 predicts that when mutation rates are high and a significant proportion of mutations are deleterious, a kind of irreversible ratchet.
