kinszelekció
Kinszelekció, a term originating from Hungarian, refers to the selection of a particular gene or trait within a kinship group that is advantageous for the survival and reproduction of related individuals. This concept is closely tied to the principles of kin selection in evolutionary biology, which explains altruistic behaviors among relatives. The underlying idea is that individuals may sacrifice their own direct reproductive success to aid their relatives, provided that the benefit to the relatives' reproductive success outweighs the individual's cost. This altruism is favored by natural selection because it indirectly increases the frequency of the altruistic individual's genes in the population through their shared genes with relatives.
The degree of altruism observed in kin selection is often proportional to the degree of relatedness. For
