About Hardy-Weinberg Equilibrium

The Hardy-Weinberg principle describes the genetic equilibrium of a population under ideal conditions. It predicts allele and genotype frequencies from one generation to the next.

Key Formulas:

  • p + q = 1 (allele frequencies)
  • p² + 2pq + q² = 1 (genotype frequencies)
  • AA: p², Aa: 2pq, aa: q²

Assumptions:

  • Large population size
  • Random mating
  • No mutation, migration, or selection

Applications:

  • Population genetics
  • Estimating carrier frequencies
  • Evolutionary biology
