The distribution of fitness effects during adaptive walks using a simple genetic network
N. L. V. O'Brien, B. Holland, J. Engelstaedter, D. Ortiz-Barrientos
This study models adaptation using a genetic network and finds that fitness effect distributions differ from theoretical expectations, showing fewer large-effect beneficial mutations and a bimodal distribution in the network model.
