ID 2 to 4 are surviving, but ID 5 is not. Than the absolute fitness for year x4 would be 1,1,1,0 (for ID 2 to 5). I wonder how to calculate a relative fitness. Like the citation basically. $\endgroup$ –

WebIn evolutionary biology, inclusive fitness is one of two metrics of evolutionary success as defined by W. D. Hamilton in 1964: . Personal fitness is the number of offspring that an individual begets (regardless of who rescues/rears/supports them); Inclusive fitness is the number of offspring equivalents that an individual rears, rescues or otherwise supports … WebMay 14, 2024 · The fitness ( w) of the recessive phenotype is thus 80% or 0.8. Their relative disadvantage can also be expressed as a selection coefficient, s, where (18.6.3) s = 1 − w In this case, (18.6.4) s = 1 − 0.8 = 0.2. The change in frequency of the dominant allele ( Δ p) after one generation is expressed by the equation

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.
