Genetic drift of an allele frequency

 Four simulated populations each start with a frequency of 0.50 for a hypothetical allele whose frequency fluctuates randomly in each population over 30 generations. The allele eventually becomes fixed in population 1, is eliminated in population 4, and is still present in populations 2 and 3 at distinct frequencies Four simulated populations each start with a frequency of 0.50 for a hypothetical allele whose frequency fluctuates randomly in each population over 30 generations.
