- 4. the amount of diversity of genes within a population of organisms
- 5. a type of behavior that is instinctual and does not have to be learned or practiced
- 7. an organism's ability to survive and reproduce in its environment
- 8. the variety of genetic material or characteristics in a species
- 9. any behavior or change in an organism that affects its ability to survive and reproduce
- 10. an idea that multiple species can evolve from a single species
- 12. the process by which organisms that are better able to survive and reproduce pass on their desirable traits to their offspring
- 13. genetic engineering where missing or damaged genes are replaced with normal genes
Down
- 1. when a population of organisms in a species becomes genetically isolated from the rest of the species and develops different mutations, causing them to begin evolving into a separate species
- 2. the transfer of alleles from one population to another
- 3. random changes in the frequency of characteristics in a gene pool
- 6. the type of selection when intentional breeding of organisms, such as animals and plants, to produce offspring with desirable traits
- 11. a theory that explains that modern organisms came from a common ancestor
