Across
- 2. beneficial traits that help an organism to survive
- 3. comparative studies that compares similarities in embryos
- 6. change in the allele frequency of a population over time
- 7. group of organisms that can reproduce with each other and form viable offspring
- 9. population is separated by geographic barrier causing separation of gene pool
- 10. drives evolution, organisms with adaptations survive and reproduce passing on those traits to the offspring causing a change in gene pool over time
- 12. all the alleles in one population
- 13. evidence that organisms existed in past and show transitional species
- 14. structures that are similar in different species that suggest a shared common ancestor
Down
- 1. comparative studies that compare similarities in structures to determine relationships
- 4. diversity in a population
- 5. structures that do not seem to have a function, but did in ancestors
- 8. formation of new species
- 9. random acts that affect a population's genetic variation
- 11. individuals entering or leaving populations changing allele frequency
