Question

Quizplus · Accepted Answer

Neutral mutations are not acted upon by natural selection and therefore can be fixed in a population through the process of random genetic drift. This is because the frequency of neutral mutations is not influenced by their fitness effects, so they can increase or decrease in frequency randomly over time due to chance events, such as genetic drift.
