Fitness of RNA Virus Decreased by Muller's Ratchet

Summary of the Article

The reason for existence of sex remained an unsolved problem in the field of Biology. Mutation occurred could be deleterious on average. Evolution of sex can be accounted to the raised mutation rate. However higher mutation rate could cause genetic drift in less population because individuals who are mutation free can be lost. Muller noted in the Populations which are asexual that the weights of deleterious mutations have increased like a ratchet manner and the loss which had been incurred is irreparable. As ...
