  • What does it mean that populations are in Hardy-Weinberg Equilibrium?
  • –Answer - there is no evolution happening in that population

  • What are the five conditions of the H-W equilibrium?
  • –Answer No mutation. Random mating No gene flow Very large population size.No natural selection

  • How does HW equilibrium relate to evolution?
  • –Answer If in HW equilibrium, its not evolving

  • What is genetic drift?
  • –Answer random change in allele frequency

  • Does genetic drift affect small or large populations more?
  • –Answer small

  • How does genetic drift effect endangered species managment?
  • –Answer Endan- gered species have smaller population sizes, and due to genetic drift they may also have decreased fitness, increased susceptibility to disease and parasites, and an overall diminished ability to respond and adapt to environmental or biological stressors

  • What is natural selection?
  • –Answer mechanic of evolution 1 / 2
