In evolutionary biology, inclusive fitness is one of two metrics of evolutionary success as defined by W. D. Hamilton in 1964: • Personal fitness is the number of offspring that an individual begets (regardless of who rescues/rears/supports them) • Inclusive fitness is the number of offspring equivalents that an individual rears, rescues or otherwise … Webquantitative genetic equations for inclusive fitness and group selection. It also shows that the group-selection model is no more general than the inclusive-fitness viewpoint. These models serve a role that is different from, but not inferior to, …
