Evolution

2. preserved remains or traces of ancient organisms
4. trait controlled by 2 or more genes
7. nature provides the inherited variation and humans select those variants they find useful
9. change in frequency of alleles in a population over time
10. isolation can develop from behavioral, geographic, or temporal isolation
11. selection when phenotypes at upper and lower ends of curve have higher fitness than individuals near middle

1. change in allele frequency following a dramatic reduction in the size of a population
3. all genes present in a population
5. when allele frequencies are not changing
6. describes how well an organism can survive and reproduce
8. principle that allele frequencies in a population should remain constant unless one or more factors causes them to change
