Populations

• Give the two equations of the Hardy-Weinberg Principle

  p + q = 1

  p2 + 2pq + q2 = 1
• Define a gene pool

  All the alleles in a population
• Hardy-Weinberg principle assumes the frequency of dominant and recessive alleles remain the same as long as?

  1. There are no mutations
  2. The population is isolated - no movement of alleles in or out
  3. There is no selection - all alleles are equally as likely to be passed on
  4. The population is large, so no genetic drift
  5. Mating within the population is random
