Practice question · Multiple choice
Parent-offspring conflict theory predicts weaning disputes even though both parties want the offspring to survive. Why does shared interest not prevent the conflict?
Hints
- Write down the relatedness of the offspring to itself and to a future sibling.
- Both want survival, the disagreement is about how much.
Show the answer
B. Because it is related to itself by 1 and to a sibling by 1/2
Why
Trivers' insight is that partial genetic overlap gives partially overlapping interests. The parent is equally related to all its offspring; each offspring is not, so they disagree about when investment should stop.
