Kuinka laskea Selection Coefficient
Mikä on Selection Coefficient?
The selection coefficient (s) quantifies the fitness disadvantage of a genotype. If the fittest genotype has relative fitness 1, a genotype with fitness (1−s) has selection coefficient s.
Vaiheittainen opas
- 1s = 1 − w_aa/w_AA
- 2Allele frequency change: Δq ≈ −sq²p/(1−sq²)
Ratkaistut esimerkit
Syöte
w_AA=1.0 · w_aa=0.7
Tulos
s = 0.3 (30% fitness reduction)
Moderate selection against recessive
