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.

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".

WebHamilton's rule leads to two conclusions. The first is that altruism is limited to kin, and the second is that __________ acts of altruism are reserved for close kin. more costly FEEDBACK: Hamilton's rule shows us that altruism can be an evolved trait when it is only for interactions between kin. WebWilliam Hamilton first published his theory of kin selection in 1963 and 1964. The best way to understand the importance of kinship is to take a gene's eye view of evolution and natural selection. For while natural selection acts on individuals (i.e. it is individuals that die or reproduce), it is the genes that are being preserved.
