An absolute fitness larger than 1 indicates growth in that genotype's abundance; an absolute fitness smaller than 1 indicates decline. Relative fitness. Whereas absolute fitness determines changes in genotype abundance, relative fitness determines changes in genotype frequency. Ver mais 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, … Ver mais Fitness is often defined as a propensity or probability, rather than the actual number of offspring.
