Intragenomic Conflict over Bet-Hedging

J. F. Wilkins, T. Bhattacharya

This paper models evolutionary bet-hedging in imprinted gene systems, showing that paternally inherited alleles reduce reproductive variance while maternally inherited alleles increase it, linking to risk-averse and risk-tolerant behaviors respectively.
