Parent-offspring conflict over reproductive efforts: Variations upon a theme by Charnov

Lundberg, S. and Smith, Henrik G. LU (1994) In Journal of Theoretical Biology 170(2). p.215-218
Abstract
A novel formulation of the theory of parent-offspring conflict is proposed. The basis of this formulation is an application of traditional life-history theory in combination with simple genetic arguments. The advanatage with this approach is conceptual, and the formulation is not in variance with earlier studies in the area. Parent-offspring conflict is, in our forumlation, not seen as a conflict between individuals, but as a tradeoff-an age-specific selection pressure acting on a trait, which is favourable when an individual is offspring and disadvantageous when it becomes parent. Using an ESS approach we investigate a simple offspring-wins problem: we find that a gene causing assertiveness of offspring will increase when rare, because... (More)
