1
Q
Conditions of Hardy Weinberg
A
Large population
Random mating
No net mutation
No migration
No natural selection
2
Q
Agents of evolutionary change
A
Mutations- change in DNA of an individual
Gene flow- net movement of alleles from one population to another
Non random mating- preventing individuals with certain phenotypes from mating
Genetic drift- due to small populations
Natural selection- when a mutation produces a phenotype
3
Q
Founder effect
A
Gene pool change that occurs when a few individuals start a new isolated population
4
Q
Bottleneck effect
A
The gene pool change that results from a rapid decrease in population size
5
Q
Primary Sucession
A
- No soil present
6
Q
Secondary Sucession
A
The recolonization of an area after an ecological disturbance
- soil is still present
