The Hardy-Weinberg Principle

The Hardy-Weinberg Principle

1. Predicts that the frequency of alleles of one gene in a particular population will the same from generation to generation

   • needs 5 assumptions
     • No mutations arise
     • there is no movement of organisms into and out of a population (migration)
     • mating within the population is random
     • large population
     • all genotypes have the same chance of reproductive success

2. A = Dominant allele , a= recessive allele, p= frequency of allele A in gene pool , q= frequency of allele a in gene pool

   • p+q= 1.0
   • p2 = homozygous dominant, q2= homozygous recessive, 2pq= heterozygous dominant
