Multiple choice

Which of the following is a type of altruism in which individuals help others who are not genetically related to them?

  1. Kin selection

  2. Reciprocal altruism

  3. Group selection

  4. Empathy-based altruism
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Reciprocal altruism is a type of altruism in which individuals help others who are not genetically related to them, in the expectation that they will receive help from them in the future.

Multiple choice
