WebIn normal sexual reproduction, a gene that is "fair" has 0.5 + 0.5p chance of being passed on to the next generation (where p is the proportion of the population that has the gene). 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.
