Talk Abstract

In the recent past there have been many controversial claims on the propensity of epistatic interactions in long-term evolution. However, claims were mostly qualitative and lacked a formal modeling approach. In this talk I will present a formal model of epistasis in molecular evolution that is based on a simple concept which we termed a fitness matrix. Time permitting I will talk about our recent data on the quantification of epistatic interactions among alleles segregating in the human population.
