What changes in the population can lead to gene drift?
| July 4, 2021 | education
Gene drift is an evolutionary mechanism in which the allele frequencies of a population change over generations due to randomness (sampling error).
Gene drift occurs endlessly in all populations, but its effects are greatest in small populations.
Gene drift can have serious consequences when a population is drastically reduced in size by a natural disaster (bottleneck effect) or when a small group breaks away from the main population to find a colony (founder effect).
