The evolutionary force of recombination is lacking in asexually reproducing populations. As a consequence, the population can suffer an irreversible accumulation of deleterious mutations, a phenomenon known as Muller's ratchet. We formulate discrete and continuous time versions of Muller's ratchet. Inspired by Haigh's (1978) analysis of a dynami-cal system which arises in the limit of large populations, we identify the parameter γ = N λ/(N s · log(N λ)) as most important for the speed of… CONTINUE READING
