Across
- 3. Collection of all the alleles present in a population.
- 8. Any characteristic that increases the fitness of an individual.
- 12. Selection within a population due to human interference and selection of desired traits.
- 13. Refers to the differences among individuals in a population.
- 14. Describes the movement of genes/alleles/individuals between 2 neighboring populations - makes populations more alike.
- 15. Migration of individuals out of a population.
- 16. Migration of new individuals into a population.
- 17. The idea that those individuals best suited to their environment will achieve higher fitness.
- 19. Measurement of the ability of an individual to survive and reproduce successful offspring.
- 20. A desired or commodity in an ecosystem - individuals of a population will compete for these.
Down
- 1. State of genetic equilibrium characterized by a large population, no migration, no natural selection, no mutations, and random mating.
- 2. Isolation of a population due to differences in the timing of mating.
- 4. Isolation of a population due to physical barriers such as a fence, mountain range, or body of water.
- 5. Group of individuals of the same species that live in the same area at the same time and can interbreed.
- 6. Random changes in allele frequencies attributed to luck, not fitness.
- 7. Type of natural selection in which individuals with one extreme phenotype have an advantage and the other extreme is selected against.
- 9. Type of natural selection in which individuals with the average phenotype have an advantage and the extremes are selected against.
- 10. Isolation of a population due to differences in communication, mating rituals, or other behaviors.
- 11. Type of natural selection in which individuals at either extreme of the bell curve achieve higher fitness and average is selected against.
- 18. Percent of individuals of a population that have a particular trait - expressed as a number between 0 and 1.
