Beneficial fitness effects are not exponential for two viruses.

Journal of molecular evolution - 1 Oct 2008

Abstract excerpt

The distribution of fitness effects for beneficial mutations is of paramount importance in determining the outcome of adaptation. It is generally assumed that fitness effects of beneficial mutations follow an exponential distribution, for example, in theoretical treatments of quantitative genetics, clonal interference, experimental evolution, and the adaptation of DNA sequences. This assumption has been justified...
