Hardy-Weinberg Principle

• Gene Pool


  All the alleles of all the genes within a population at one time
• Population


  All the individuals of one species in one area at a time
• Allele Frequency


  The proportion of an allele within the gene pool
• Hardy-Weinberg Formula


  $p^2 +$$2pq +$$q^2 =$$1$ alongside $p +$$q =$$1$
• p = frequency of dominant allele
• q = frequency of recessive allele
• $p^2$ = frequency of homozygous dominant genotype
• $q^2$ = frequency of homozygous recessive genotype
• $2pq$ = frequency of heterozygous genotype
