Across
- 5. movement of genes into or out of a population
- 9. type of reproductive isolation due to different mating seasons
- 11. separation of a species or population so that they can no longer interbreed
- 12. type of reproductive isolation where physical barriers prevent interbreeding
- 13. type of reproductive isolation where individuals separate based on courtship rituals
- 14. sudden change in allele frequency following major environmental event
Down
- 1. selection of mates based on heritable traits
- 2. formation of a new species
- 3. in small populations, allele frequency due to random chance
- 4. form of natural selection favoring the moderate (middle)
- 6. form of natural selection favoring one extreme (end)
- 7. all the genes present in a population
- 8. change in allele frequency due to migration of small population
- 10. form of natural selection favoring both extremes (ends)
