Adaptive walks and distribution of beneficial fitness effects.

Evolution; international journal of organic evolution - 1 Apr 2014

Seetharaman Sarada, Jain Kavita

Abstract excerpt

We study the adaptation dynamics of a maladapted asexual population on rugged fitness landscapes with many local fitness peaks. The distribution of beneficial fitness effects is assumed to belong to one of the three extreme value domains, viz. Weibull, Gumbel, and Fréchet. We work in the strong selection-weak mutation regime in which beneficial mutations fix sequentially, and the population performs an uphill...
