  1. Fisher’s exact test testing the association between switches from ‘Incorrect to Correct’ and ‘Correct to Incorrect’ answers per question and by method of instruction (Genie 2017 and Non-Genie 2017)
  2. ± Significant p-values
  3. * Misconceptions (Price et al. 2014)
  4. 1. Genetic drift is unpredictable because it has a random component
  5. 2. Genetic drift is natural selection/adaptation/acclimation to the environment that may result from a need to survive
  6. 3. Genetic drift is not evolution because it does not lead to directional change that increases fitness
  7. 4. Natural selection is always the most powerful mechanism of evolution, and it is the primary agent of evolutionary change
  8. 5. Genetic drift is random mutation
  9. 6. Genetic drift is gene flow or migration
