Hardy-Weinberg equilibrium (HWE) describes how allele frequencies change over time when certain conditions are met
Hardy Weinberg Equation predicts the frequency of alleles in a population
q = recessive
p = dominant
Assumptions made by HWE
Population is large
Organisms are diploid
Organisms reproduce only by sexual reproduction
No changes occurring to the genetic diversity of the population (eg immigration/emigration, mutation, directional selection)
Mating is random
Allele Frequencies are equal in both sexes
There is no overlap between generations of organisms
Hardy-Weinberg Equation:
p + q = 1
p2 + q2 + 2pq = 1
p2 = homozygous dominant (BB)
q2 = homozygous recessive (bb)
2pq = heterozygous (Bb)
