Allelic Frequency - Simulation

Adjust the initial allelic frequency and population size to the right.

Five selectively neutral genes are present in the population for this simulation. Notice that the initial allelic frequency f(a) determines the proportion of alleles that become fixed as opposed to lost. Also note that as the population size (N) is increased, the effect that genetic drift has on the population size is decreased.

If you continue to press run, without pressing reset, the all alleles will eventually become fixed or extinct. Since there is no mutation in this simulation, the lost alleles cannot be recovered.
