Across
- 5. Refers to the differences among individuals in a population
- 6. Isolation of a population due to differences in the timing of maiting
- 8. Percent of individuals of a population that have a particular trait-expressed as a number between 0 and 1
- 10. Migration of new individuals into a population
- 11. Random changes in allele frequencies due to luck,not fitness
- 14. Selection within a population due to human interference and selection of desired traits
- 15. When a small part of a population is separated from the rest and colonizes a new area-they often respond differently to natural selection pressures
Down
- 1. Migration of individuals out of a population
- 2. Any characteristic that increases the fitness of an individual
- 3. Collection of all alleles present in a population
- 4. A necessary or desired commodity in an ecosystem-individuals of a population will compete for these
- 7. Group of individuals of the same species that live in the same area at the same time and can interbreed
- 9. When organisms will impersonate other organisms to increase fitness
- 12. The idea that those individuals best suited for their environment will achieve higher fitness
- 13. Measurement of the ability of an individual to survive and reproduce successful offspring
