The relative number of an individual's alleles that are passed on from generation to generation, either as a result of his or her own reproductive success, or that of related individuals.
an individual's own fitness plus his or her effect on the fitness of any relative.
The expansion of the concept of the fitness of a genotype to include benefits accrued to relatives of an individual since relatives share parts of their genomes. Hence an apparently altruistic act toward a relative may in fact enhance the fitness of the individual performing the act.
The sum of an individual's fitness and the fitness of all of the individuals relatives, weighted by their degree of relatedness.
The sum of an individual's own fitness (the effect of producing its own offspring: the individual selection component) plus its influence on fitness in relatives other than direct descendants (the kin selection component).
Sum of Direct Fitness, and Indirect Fitness
the fitness individuals derive from increasing the survival of their relatives' offspring; the young of their relatives share some percentage of their genes and by helping them to survive they are increasing the opportunity for those genes to continue to be passed on
Fitness defined by personal reproductive success as well as by relatives sharing an individual's genes. 826
The overall fitness to survive to reproductive age (Darwinian fitness). Lacustrine Of or pertaining to lakes: dwelling in or on lakes: formed by lakes. Littoral Belonging to the sea-shore, to lands near the coast, the beach, the space between high and low tide marks or water a little below the low tide mark. Inhabiting the shore or shallow water of a lake or sea.
The idea that fitness is measured by the success of one's genes, whether possessed by the individual or by that individual's relatives.
Inclusive fitness encompasses conventional Darwinian fitness with the addition of behaviors that contribute to an organism’s individual fitness through altruism. An organism’s success, from the gene's point of view, ultimately depends on leaving behind the maximum number of replicas of its genes present within a population. Until 1964 it was generally believed this was done only by leaving the maximum number of viable offspring possible.
