Which equation calculates the indirect fitness benefit of altruistic behavior and kin selection?

Question

Quizplus · Accepted Answer

The equation that calculates the indirect fitness benefit of altruistic behavior and kin selection is B x r, where B is the benefit gained by the recipient of the behavior and r is the coefficient of relatedness. This equation shows how much genetic similarity the altruistic individual shares with the recipient and therefore the likelihood that shared genes will be passed on through the recipient's reproduction. Option A (C x r) is not relevant as it refers to the cost of the behavior, which is not needed to calculate indirect fitness. Option C (B ÷ r) and option D (B + r) are also incorrect as they do not correctly represent the calculation of indirect fitness benefit.
