Fitness of RNA virus decreased by Muller's ratchet.

Nature - 29 Nov 1990

Chao L

Abstract excerpt

Why sex exists remains an unsolved problem in biology. If mutations are on the average deleterious, a high mutation rate can account for the evolution of sex. One form of this mutational hypothesis is Muller's ratchet. If the mutation rate is high, mutation-free individuals become rare and they c...
