This kind of reproduction does not alter the frequency of the gene in the population. I think that a Fisherian runaway occurs when a gene (or genes) cheats the system.

Web5. A prediction from Fisher’s theory of sexual selection (the “runaway process”) is that: a) mating preferences should evolve to increase female fitness. b) the evolution of mating preferences should predate the evolution of exaggerated male traits. c) sexual selection always favours traits that increase survival.
