Which of the following statements accurately describes a key characteristic or effect of genetic drift?

  • A: Genetic drift consistently favors certain alleles over others, leading to predictable changes.
  • B: Genetic drift is significant primarily in large populations, where chance events have a greater impact.
  • C: Genetic drift can lead to the loss of genetic variation within populations.
  • D: Genetic drift typically increases the frequency of beneficial alleles, enhancing adaptation.

Explanation

Point 3 under 'Effects of Genetic Drift: A Summary' states that genetic drift can lead to a loss of genetic variation within populations by eliminating alleles.
