2. state of genetic equilibrium characterized by a large population, no migration, no natural selection, no mutations, and random mating
4. individuals with the average phenotype have an advantage and the extremes are selected against
11. isolation of a population due to differences in the timing of mating
12. migration of new individuals into a population
13. the idea that those individuals best suited to their environment will achieve higher fitness
14. when a small part of a population is separated from the rest and colonizes a new area
16. individuals at either extreme of the bell curve achieve higher fitness and the average is selected against
17. selection within a population due to human interference and selection of desired traits
18. refers to the differences among individuals in a population
19. describes the movement of genes/alleles/individuals between two neighboring populations

1. isolation of a population due to differences in communication, mating rituals, or other behaviors
3. when a population experiences a rapid, drastic reduction in the number of individuals in the population
5. collection of all the alleles present in a population
6. individuals with one extreme phenotype have an advantage and the other extreme is selected against
7. any characteristic that increases the fitness of an individual
8. random changes in allele frequencies attributed to luck, not fitness
9. isolation of a population due to physical barriers
10. percent of individuals of a population that have a particular trait
14. measurement of the ability of an individual to survive and reproduce successful offspring
15. migration of individuals out of a population
