Population Dynamics

2. allele frequencies in a population change as a result of random events or chance.
4. Individuals are not evenly spaced throughout the area.
5. Individuals are evenly spaced throughout the area.
7. Type of isolation that includes physical separation of members of a population.
10. both extreme variations of trait have greater fitness.
12. Type of isolation that includes behavior barriers to successful breeding.
13. total genetic information available in a population.
15. The hypothesis that evolution happens rapidly and is broken up by times of little change.
16. one extreme form of trait has greater fitness.
17. Leaving a current population.
18. Individuals are clustered in groups throughout the area.

1. average form of trait has highest fitness.
3. Entering a new population.
6. when the frequency of an allele or genotype appearing in a population doesn’t change from generation to generation.
8. the process of genes moving from one population to another.
9. Reproductive isolation that happens before fertilization.
11. Reproductive isolation that happens after fertilization.
14. The hypothesis that evolution occurs at a slow, constant rate.
