We ran a simulation that graphed the popuulation and allele frquencies (A and B alleles) of three populations. For a simulation where there is no genetic drift, mutation or migration affecting the population, there is still a slow, steady change of the frequency of the A allele over time (all three poplations' allele A frquencies seemed to go towards an allele frequency of 0.500).

a) What is the factor causing the linear curves to all go slowly and steadily towards an allele frequency of 0.500?

b) How is it that allele frequencies can still fluctuate in absence of genetic drift, migration and mutation?
