Talk:Genetic drift/to do

To Do

 * Generalize example to differing initial frequencies
 * Generalize example to combined selection/drift
 * Formula for probability of drift
 * Formula for expected (magnitude) of drift
 * Role in extinction, fixation, substitution
 * Probability of substitution
 * Balance between mutation influx and extinction/substitution
 * Neutral evolution
 * Drift -> divergence -> finds new points where selection exists
 * Gene duplication -> more drift -> new function
 * Loss of unused traits (example: sight in dark cave)
 * Diffusion models of genetic drift
