    Eduncle Best Answer

    Five assumptions of a Hardy-Weinberg population
    (1)            No Selection
    (2)            No Mutation
    (3)            No Gene Flow-No migration between populations to change allele frequencies
    (4)            Infinite Population is necessary because the larger the population size is, the harder to change the allele frequency.
    (5)            Random Mating which is pretty much what it says: Mating being based on nothing other than pure chance, making it random. Hence any deviation from these                         assumptions will cause allele frequencies to change over time.
