Genetic drift is random change in allele frequencies due to chance — particularly influential in small populations where sampling error is large relative to gene pool size.
Trin-for-trin guide
- 1Variance per generation: p(1-p)/(2N)
- 2Small N → large fluctuations → faster drift to fixation or loss

Input
p=0.5 · N=50
Resultat
σ per generation = ±5%
Small population drifts fast
