Biology

5. reproductive success and reflects how well an organism is adapted to its environment.
7. something in the environment that is needed by other orgainsms
8. a reproductive barrier that prevents interbreeding
9. sharp reduction in the size of a population due to environmental events
12. the physical separation due to geographic barriers
16. he process by which humans choose individual organisms with certain phenotypic trait values for breeding
17. the transfer of genetic material from one population to another
19. phenotype is favored over other phenotypes
20. the set of all genes

1. the loss of genetic variation in a population
2. an organism that looks like another object
3. how common an allele is in a population
4. the process through which populations of living organisms adapt and change
6. the change in the frequency of an existing gene variant in a population due to random chance
10. extreme values for a trait are favored
11. when species are reproductively isolated from others due to differences in behavior
13. the evolutionary process whereby an organism becomes better able to live in its habitat or habitats
14. when you come to
15. when you leave
18. a group of organisms
