Genetic Drift Simulator
Explore how random genetic drift shapes allele frequencies over time in finite populations.
This interactive app lets you simulate the fate of an allele under drift, experiment with population size, number of generations, initial allele frequency, and number of replicates, and see how randomness can lead to fixation or loss—even in the absence of selection.
This interactive app allows you to: - Simulate allele frequency changes under genetic drift for different population sizes and generations. - Visualize the stochastic trajectories of multiple replicates. - Observe how population size and initial frequency affect the probability of fixation or loss. - Build intuition for the role of chance in evolution and the importance of genetic drift in small populations.
