" Random changes in allele frequency" best describes genetic drift

Explanation:

The process where the allele frequencies within the population change accidentally alone results in sampling error from one generation to another. It is random process which further leads to large change in population in short time period . Random change is the frequency present in the existing gene variant in the population as a result of 'random sampling'. The allele frequencies are the reflection of the genetic diversity. It can also be due to the mutations that have been introduced into the population.
