Across
- 2. type of isolation where courtship behaviour prevents the hybridization of closely related species
- 5. the formation of new species through evolution.
- 7. type of speciation that occurs when when a population divides into different species while inhabiting the same habitat.
- 10. type of isolation that occurs due to organisms reproducing at different times, resulting in reproductive isolation
- 13. type of evolution where species sharing a common ancestry become more distinct due to differential selection pressure leading to speciation
- 14. a group of the same species living in the same area at the same time
- 15. the variety of organisms in a ecosystem.
- 17. a group of organisms that can interbreed and produce fertile offspring
- 18. change in heritable characteristics
Down
- 1. a form of sympatric speciation results in more than two sets of homologous chromosomes and occurs most commonly in plants as a result of errors during meiosis.
- 3. type of speciation that occurs due to geographical isolation
- 4. different structures with the same function
- 6. offspring of two different species
- 8. type of isolation that occurs when physical differences between organisms prevent sexual intercourse.
- 9. similar structure difference function
- 11. last name of the biologist that proposed the theory of natural selection
- 12. type of breeding where humans choose the organism with favourable trait to breed to produce offspring that can inherit the trait
- 16. type of limb that is an example of homologous structure
