Formally, genes should increase in frequency when $${\displaystyle rB>C}$$ where r = the genetic relatedness of the recipient to the actor, often defined as the probability that a gene picked randomly from each at the same locus is identical by descent.

Hamilton
WebHamilton showed mathematically that, because other members of a population may share one's genes, a gene can also increase its evolutionary success by indirectly promoting the reproduction and survival of other individuals who also carry that gene. This is variously called "kin theory", "kin selection theory" or "inclusive fitness theory". WebKin selection follows Hamilton's Rule, which suggests that if the benefit of a behavior to a recipient, taking into account the genetic relatedness of the recipient to the altruist, … fish lake national forest travel map
