Webthis issue is Fisher's geometric model and related phenotypic landscape models. However, it suffers from several restrictive assumptions. In this paper, we intend to show how several of these limitations may be overcome. We then propose a model of f(s) that extends Fisher's model to account for arbitrary mutational and selective interactions WebFisher's geometric model has been widely used to study the effects of pleiotropy and organismic complexity on phenotypic adaptation.

Each trait has an optimal value, and the fitness of trait combinations is a decreasing function of the distance to the optimal trait combination.
