Allele Frequencies

Today we learned about the frequencies of different alleles in different populations. We learned how to calculate the frequency using two equations : p² + 2pq + q² = 1 and p + q = 1. We experimented with this by having four alleles and mating with other members of our class randomly. We also experimented with genetic drift, by separating our class in half and only mating within our half. We noticed that one population’s frequencies stayed the same, and the other population’s frequencies changed to having more dominant alleles than recessive.
