Recombination and the immortality of the germ line

  title={Recombination and the immortality of the germ line},
  author={Graham Bell},
Asexual populations irreversibly accumulate mildly deleterious mutations through the occasional stochastic loss of their least-loaded line, a process known as “Muller’s Ratchet”. This paper explores the dynamics of this process, and the role of recombination in halting the Ratchet. Simulation studies show that an optimal class comprising n, individuals is lost in about lOn, generations, implying that adaptedness may deteriorate rather rapidly in geological time. Asexual organisms will persist… CONTINUE READING
