Which of the following best describes genetic drift? (2022)
  1. Change in allele frequencies due to random sampling
  2. Change in allele frequencies due to natural selection
  3. Change in allele frequencies due to mutation
  4. Change in allele frequencies due to gene flow

Questions & Step-by-Step Solutions

Which of the following best describes genetic drift? (2022)
  • Step 1: Understand what genetic drift means. It is a process that causes random changes in the genetic makeup of a population.
  • Step 2: Learn about allele frequencies. Alleles are different versions of a gene, and their frequencies refer to how common they are in a population.
  • Step 3: Recognize that genetic drift happens by chance. It is not caused by natural selection or environmental factors.
  • Step 4: Note that genetic drift has a bigger impact on small populations. In larger populations, random changes are less noticeable.
