Natural selection works to maximize fitness, because traits can only be selected for if they are … WebDifferential fitness is the third of Darwin's four postulates for natural selection. It states that survival and reproduction rates vary between individuals. Fitness differentials are widespread and detectable throughout nature. This fitness differential is visible in several ways, and it can be detected throughout nature. It can be based on behavioral …
Fitness (often denoted $${\displaystyle w}$$ or ω in population genetics models) is the quantitative representation of individual reproductive success. It is also equal to the average contribution to the gene pool of the next generation, made by the same individuals of the specified genotype or phenotype.
