- Disequilibrium may be generated by the chance background on which mutations appear or random drift in finite populations.
- When D > 0 (Vg _), selection acts more rapidly and D dissipates.
- When D < 0 (Vg _), selection acts less rapidly and D remains.
- Drift with selection generates, on average, negative disequilibrium that reduce the response to selection
- Selection for increased sex/rec, especially when there is strong selection, a small population size, and low initial sex/rec.
