Inclusive fitness in animals
WebInclusive fitness is an individual’s ability to pass down their genes—both through their offspring and the offspring of close relatives with shared genes. If an animal helps a close relative improve their reproductive success, this increases the animal’s inclusive fitness, preserving the behavior in the gene pool.
