WebFitness (biology) Fitness (often denoted 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 … 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 example homozygous for allele A at a particular locus. Thus the phrase ’expected number of offspring’ means the average number, not the number produced by some one individual.

WebDec 9, 2002 · In the century and a half since the publication of On the Origin of Species biologists have all too often reinforced this objection by actually so defining fitness. For example, C.H. Waddington writes, in Towards a Theoretical Biology (1968, 19), that the fittest individuals are those that are “most effective in leaving gametes to the next ... WebFitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group). Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).
