Yeah, it would have to be at least 3 individuals mating. And there would be some weird dynamics: the individual that feels less fit than the partners would have a weaker incentive to mate, because its genes would be less likely to continue. Then the other partners would have to offer some bribe, maybe take on more parental investment. Then maybe some individuals would pretend to be less fit, to receive the bribe. It’s tricky to think about, maybe it’s already researched somewhere?
