Question

Which of the following is an accurate representation of the rule that has been proposed to predict when a gene for an altruistic behavior will spread in a population?

B) B/C < 1/r
C) B/r > 1/C
D) C/r = 0

The correct representation of the rule proposed to predict when a gene for an altruistic behavior will spread in a population is Hamilton's rule, which is often summarized as rB > C, where r is the genetic relatedness between the altruist and the recipient, B is the benefit to the recipient, and C is the cost to the altruist. None of the options provided exactly match this formula, but option A, B/C > 1/r, is a rearrangement of Hamilton's rule and thus the closest correct representation.
