Reciprocal altruism can be best explained with a model proposed by robert trivers in 1971. trivers hypothesized that if one individual (a) pays some cost to another individual (b), but the cost is recovered at some point in the future (when b a), then natural selection might favor behaviors that lead to this type of reciprocity. in which of the following situations is reciprocal altruism likely to occur?

Reciprocal altruism is one of the altruism behaviors in which an individual organism helps in increasing the fitness of another organism by reducing the fitness of itself temporarily in expectation of the same behavior from another organism in the future later.

It takes place in the same set of organism partners which is a continuous interaction ion in stable groups of organisms.

Thus, the correct answer would be - an ongoing interaction in the same set of partners.

in situ hybridization has been widely used for research applications, including clinical cytogenetics, gene mapping, tumor biology and studies of chromosome evolution.
