- 2. A trait that is beneficial to an organism and will likely be chosen by natural selection.
- 4. The variety of gene combinations that exist within a population.
- 7. A group of organisms with similar characteristics that are able to interbreed or exchange genetic material.
- 8. Matching genes that come from the biological mother and father. Often, they are slightly different causing mutations.
- 11. A group of interacting individuals of the same species located in the same area.

- 1. Charles' Darwin's theory of 'survival of the fittest'. Process by which organisms with favorable traits produce more successful offspring than organisms with less-favorable traits, causing the favorable traits to become more common in the population.
- 3. A characteristic of an organism; can be genetic or acquired.
- 5. A process by which a population becomes better suited to its environment by increasing the frequencies of alleles that provide benefits to survival and reproduction.
- 6. Organisms of the same species that are at the same level of descent from a common ancestor.
- 9. The change in the gene pool of species over time that results from genetic changes passed down over successive generations.
- 10. Deoxyribonucleic acid is the molecule that carries genetic information for the development and functioning of an organism.
