Some Mathematical Considerations on the Parent-Offspring Conflict Phenomenon

A stochastic dynamic programming model for parent-offspring conflict is analysed and discussed. We discuss how the conflict is resolved and how the ultimate offspringʹs independence age is determined between parent and offspring. The results of the mathematical model indicate the possibility that the observed behaviour of parental care may change depending on the parentʹs age. This is because the compromise conclusion of the parent-offspring conflict depends on the parentʹs age: that is, essentially, on the parentʹs expected future reproductive value. Moreover, it is shown that the observed parent-offspring conflict possibly depends also on the parentʹs age.
