A
Mutations, Genetic Drift, and Gene Flow.
2
Q
Mutations
A
- Changes in genetic material.
- Raw material for evolutionary change.
3
Q
Genetic Drift
A
- Change in Gene Pool due to chance.
- –Bottleneck effect
- –Founder Effect
4
Q
Bottleneck Effect
A
Certain alleles can become under/over represented.
5
Q
