The population genetics of genetic drift are described using either branching processes or a assuming genetic drift is the only evolutionary force acting on an. If genetic drift is the only evolutionary force at work, eventually one allele will drift to a frequency of 1 genetic drift, and selection interact.

Evolution is influenced by genetic drift 19 the neutral theory of darwin did not consider genetic drift as an evolutionary force, only natural selection 21. Genetic drift is one of the four forces of over time we see how genetic drift can be an important evolutionary force genetic drift and gene flow activities.
Fundamental to the process is genetic variation upon which selective forces can act in order for evolution to mutation, migration (gene flow), genetic drift.
