Across
- 6. are similar in structure but different in function
- 7. links groups of organisms by showing current hypotheses about how evolutionary lines or lineages, branch off from common ancestors
- 8. describes evolution toward different traits in closely related species
- 10. have a similar function, but different structure
- 13. favors the intermediate phenotype
- 14. Study of embryos and their development
- 15. The selective breeding of organisms by humans for specific characteristics
- 16. favors both extreme phenotypes
- 17. all the genes present in a population
Down
- 1. favors phenotypes at one extreme
- 2. is genetic drift that occurs after start of new population
- 3. a mechanism by which individuals that have inherited beneficial adaptations produce more offspring on average than do other individuals
- 4. are remnants of organs or structures that had a function in an early ancestor
- 5. describes evolution toward similar traits in unrelated species
- 9. Change in allele frequencies over time
- 11. Preserved remains of, or traces of, ancient organisms
- 12. process by which two species evolve in response to changes in the other
