Exploring the effect of sex on empirical fitness landscapes.

The American naturalist - 1 Jul 2009

de Visser J Arjan G M, Park Su-Chan, Krug Joachim

Abstract excerpt

The nature of epistasis has important consequences for the evolutionary significance of sex and recombination. Recent efforts to find negative epistasis as a source of negative linkage disequilibrium and associated long-term advantage to sex have yielded little support. Sign epistasis, where the sign of the fitness effects of alleles varies across genetic backgrounds, is responsible for the ruggedness of the...
