Evolution and Natural Selection
Across
- 1. The transfer of genetic material from one population to another
- 4. A unicellular microorganism
- 7. The division of a single entity into tow or more parts that regenerate
- 11. The phenomenon when a population has a sudden reduction in the gene pool due to natural environmental events, natural disasters, disease, or human involvement
- 13. Changing to fit certain circumstances
- 15. Cells that contain a nucleus
- 16. reproducing where there is two separate genetic materials combined
- 17. When humans pick which animals and plants breed to create a specific outcome
- 20. Variation in the relative frequency of different genotypes
Down
- 2. a process where living organisms adapt and change
- 3. When a species dies out
- 5. When bacteria cannot be killed by antibiotics
- 6. An infective agent
- 8. The reduction in genomic variability when a small group of individuals become separated from a larger population
- 9. reproducing with only one set of DNA
- 10. cells without a nucleus
- 12. The process of animals naturally choosing a mate
- 14. A formation of new and distinct species in the course of evolution
- 18. DNA sequences
- 19. The branch of biology and medicine concerned with the study of embryos and their development
