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. Fitness can be … See more Fitness is often defined as a propensity or probability, rather than the actual number of offspring. For example, according to Maynard Smith, "Fitness is a property, not of an individual, but of a class of individuals—for … See more In order to avoid the complications of sex and recombination, the concept of fitness is restricted to an asexual population without genetic recombination. Thus, fitnesses can be assigned directly to genotypes and measured.
