hardy-weinberg equation

• principle

  • if certain conditions are met, allele frequencies of a gene within a population will not change from one generation to the next
• assumptions

  • mating must be random
  • population infinately large
  • no migration, mutation or natural selection
• allele equation 


  p+q=1
• genotype equation 


  p2+q2+2PQ=1
• P=dominant allele

  q=recessive allele

  p2=homozygous dominant

  q2=homozygous recessive

  2pq= heterozygous
