    Study Notes

    Hardy-Weinberg Equilibrium

    • Describes the genetic makeup of a population that is not evolving at a specific locus.
    • The population is in Hardy-Weinberg equilibrium if the observed data matches the expected values.
    • The condition for a population to be in Hardy-Weinberg equilibrium is:
      • the population is very large
      • there is no mutation
      • there is no genetic drift
      • there is no gene flow
      • mating is random
      • there is no natural selection
    • In a population in Hardy-Weinberg equilibrium, the frequency of alleles and genotypes remains constant from generation to generation.
    • Mendelian inheritance preserves the genetic variation in a population.
    • The Hardy-Weinberg equation describes the frequency of alleles in a population.
    • If the frequency of one allele is 0.2, the frequency of the other allele is 0.8.
    • The sum of the frequencies of the two alleles is 1.
    • The Hardy-Weinberg equation is: p^2 + 2pq + q^2 = 1.
    • The probability of a zygote having a particular allele or genotype is calculated using the Hardy-Weinberg equation.
    • The probability of a zygote having the CR allele is p^2.
    • The probability of a zygote having the Cw allele is q^2.
    • The probability of a zygote having the CwCw genotype is q^2.
    • The probability of a zygote having the CR allele in a population in Hardy-Weinberg equilibrium is p.
    • The Hardy-Weinberg equation does not require a population to be in genetic drift or mutation.
