Genetic Drift is a change is allelic frequency resulting from random events.

Sampling Error - Sampling errors are more significant in small populations.
Effective Population Size
Bottleneck
Founder Effects.

Mutation -

Assume that mutation from
- A to a = u
- a to A = v
Then equilibrium is q(hat)=u/(u+v)
