Hardy-Weinberg Law

    Cards (6)

    • Hardy-Weinberg Law
      • states that in an infinitely large interbreeding population in which mating is random.
      • There is no selection, migration, or mutation. Gene and genotype frequencies will remain constant from generation to generation.
    • Conditions for Genetic Equilibrium
      1. No Mutation in DNA Sequence
      2. No Migration
      3. A very large population in size
      4. Random Mating
      5. No Natural Selection
    • Hardy-Weinberg Equations
      • describes how a population can remain at genetic equilibrium. Genetic equilibrium occurs when there is no evolution within the population.
    • People behind the Hardy-Weinberg Law
      • Godfred Hardy
      • Wilhelm Weinberg
    • Formulas:
      p+p+q=q=11
      p2+p^2+2pq+2pq+q2=q^2=11
    • p = dominant allele
      q = reccessive allele
      p^2 = homozygous dominant allele
      q^2 = homozygous recessive allele
      2pq = heterozygous dominant allele
