Dictionary


Genetic drift is a process of random changes of allele frequencies in a given population. These changes are not driven by selection pressures. In the finite populations, the genetic drift leads to a fixation of one of the alleles, i.e. its frequency becomes 100%. Together with selection, genetic drift is considered one of the major driving forces of the biological evolution.
