Hamilton's rule describes what concept?

a) to predict which traits evolution will favor in the future, one should look to see what the species is learning today

b) the idea that genes predispose animals to exhibit kin altruism will always be favored by natural selection

c) a cost-benefit analysis that an individual performs before deciding whether to act altruistically or selfishly towards its kin

d) a cost-benefit analysis for whether selection will favor the gene(s) in question underlying a particular trait

Explanation / Answer

B) the idea that genes predispose animals to exhibit kin altruism will be favoured by natural selection.

According to the Hamilton’s rule, altruism would be favoured by natural selection if

rB > C

Where r is the relatedness or the proportion of the genes that are shared, B is the benefit to the recipient and C is the cost to the altruist.

This inequality only explains that when cost is low for the actor and benefit to the recipient is greater, as well as when the participants would be closely related, altruism would be more likely to be spread.
