Social heterosis and the maintenance of genetic diversity.

Journal of evolutionary biology - 1 Nov 2007

Nonacs P, Kapheim K M

Abstract excerpt

Genetic diversity in species is often high in spite of directional selection or strong genetic drift. One resolution to this paradox may be through fitness benefits arising from interactions of genetically diverse individuals. Advantageous phenotypes that are impossible in single individuals (e.g. being simultaneously bold and shy) can be expressed by groups composed of genetically different individuals. Genetic...
