Did you know?
WebThe inclusive fitness theory is a model for the evolution of social behaviors or traits that was proposed by W. D. Hamilton. In evolutionary biology, individual genetic success is defined as having the opportunity to pass along positive traits a maximum number of times through direct reproduction. However, researcher William Hamilton, in ... WebThis concept is known as inclusive fitness, which is the sum of an individual's own reproductive success and the reproductive success of their relatives. One example of kin selection is seen in social insects such as bees and ants. In these species, workers are often sterile and do not reproduce, but they work to benefit the queen and her ...
The concept serves to explain how natural selection can perpetuate altruism. If there is an "altruism gene" (or complex of genes) that influences an organism's behavior to be helpful and protective of relatives and their offspring, this behavior also increases the proportion of the altruism gene in the population, because relatives are likely to share genes with the altruist due to common descent. In formal terms, if such a complex of genes arises, Hamilton's rule (rbc) speci… WebJan 1, 2024 · Inclusive fitness relies in part on kin recognition and relatedness coefficients, which reflect the probability of sharing a given gene or allele between two relatives. For example, first-, second-, and third-order relatives have relatedness coefficients of 0.5, 0.25, and 0.125, respectively. Hamilton’s rule (see Eq.
