Hardy Weinberg Equation

• What are the assumptions made when using the equation?

  1. No selection of mates
  2. No mutations
  3. No migration
  4. There is a large population
  5. Mating is random
• Equation 1

  P+q =1

  • where P is a dominant allele and q is a recessive allele
• Equation 2

  p2 + 2pq + q2 = 1

  • where p is homozygous dominant
  • q is homozygous recessive
  • 2pq is heterozygous and unknown
• How can you use the Hardy-Weinberg equation to see if evolution has occured?

  Compare the allele frequencies over time.

  If there is no change, then evolution hasn't occured
