WebThe above equations depend only on the relative fitnesses of the alleles. Therefore, we can measure fitness relative to the fitness of one of the alleles (a). W a = 1 . W A = 1 + s . s is known as a selection coefficient, which measures the amount by which fitness of a type differs from the fitness of a reference type (here a).

WebIn evolution, fitness is about success at surviving and reproducing, not about exercise and strength. Of course, fitness is a relative thing. A genotype’s fitness depends on the environment in which the organism lives. The fittest genotype during an ice age, for example, is probably not the fittest genotype once the ice age is over. WebThis approach to fitness can lead us into the tautology trap: fitness defined by those that survive better (post hoc), but the change may not have been due to natural selection (e.g. drift). With true Darwinian fitnesses we would be able to predict which genotype would survive better (fitness values assigned to genotype "before" generation ...
