Consistent cooperation in a cichlid fish is caused by maternal and developmental effects rather than heritable genetic variation.

Abstract excerpt

Studies on the evolution of cooperative behaviour are typically confined to understanding its adaptive value. It is equally essential, however, to understand its potential to evolve, requiring knowledge about the phenotypic consistency and genetic basis of cooperative behaviour. While previous observational studies reported considerably high heritabilities of helping behaviour in cooperatively breeding...
