The effect of the fitness gradient on fixation probability.

Nature communications - 17 Apr 2026

Svoboda Jakub, Nemati Hossein, Tkadlec Josef, Kaveh Kamran, Chatterjee Krishnendu

Abstract excerpt

Evolutionary biology examines how the genetic and phenotypic composition of populations changes over time. An important goal is to determine the fixation probability of a single advantageous mutant that arises in a homogeneous population of N residents. Many real populations experience environmental gradients that cause mutations to be beneficial in some spatial regions but harmful in others. Here, we study the...
