| Abstract: | Models are presented showing that, under certain conditions, when multiple offspring are reared simultaneously, the magnitude of offspring selfishness is independent of offspring-offspring genetic relatedness. When the cost (θ) of the selfish offspring's behavior approaches zero, alleles causing offspring selfishness spread as long as is positive.In general, simultaneous offspring are predicted to behave more selfishly than sequential offspring.Stable equilibria between alleles for selfish and non-selfish behavior are predicted for certain selfish alleles. |
