Hardy-Weinberg Law

• 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+$$q=$$1$

  $p^2+$$2pq+$$q^2=$$1$
• p = dominant allele

  q = reccessive allele

  p^2 = homozygous dominant allele

  q^2 = homozygous recessive allele

  2pq = heterozygous dominant allele
