Questions and Answers

Which of the following best describes the 'Founder Effect'?

  • The movement of genes between populations, preserving genetic variation
  • Occurs when a species undergoes a geographical change or is introduced to new areas by humans (correct)
  • Bias caused by small samples, decreasing as sample size increases
  • A drastic reduction in population size, leading to random changes in allele frequencies

    • Which of the following is a result of 'Genetic Drift'?

  • Preservation of genetic variation between populations
  • Random fluctuations in allele frequencies (correct)
  • Increase in genetic variation within populations
  • Changes in average allele frequencies

    • Which process is responsible for the movement of genes between populations?

  • Founder Effect
  • Bottleneck
  • Gene Flow (correct)
  • Genetic Drift

    • What is the impact of a 'Bottleneck' on the allele frequencies of the survivor population?
