2. frequency of a population as a result of chance events rather than natural selection.
3. Breeding organisms with specific traits in order to produce offspring with identical traits.
6. change in allele frequencies as a result of the migration of a small subgroup of a population
7. Number of times that an allele occurs in a gene pool compared with the number of alleles in that pool for the same gene
8. A trait that helps an organism survive and reproduce
9. of reproductive isolation in which two populations reproduce at different times
11. Natural selection that favors intermediate variants by acting against extreme phenotypes
13. of reproductive isolation in which two populations have differences in courtship rituals or other types of behavior that prevent them from interbreeding
16. Form of natural selection in which the entire curve moves; occurs when individuals at one end of a distribution curve have higher fitness than individuals in the middle or at the other end of the curve
17. Ability of an organism to survive and reproduce in its environment
18. Combined genetic information of all the members of a particular population
19. of natural selection in which a single curve splits into two; occurs when individuals at the upper and lower ends of a distribution curve have higher fitness than individuals near the middle

1. Ability of an animal to look like another more harmful animal
4. involves physical barriers that divide a population into two or more groups
5. the act of concealing the identity of something by modifying its appearance
10. A change in allele frequency following a dramatic reduction in the size of a population
12. A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.
14. Any difference between individuals of the same species.
15. movement of alleles from one population to another
