7. a specific characteristic of an organism
12. biological process by which new individual organisms are produced
13. drift the change in the frequency of an existing gene variant in a population

17. an interaction between organisms or species in which both are harmed
18. type of reproduction that does not involve the fusion of gametes
19. the act or fact of living or continuing longer than another person or thing
20. occurs when species are diminished because of environmental forces

1. difference in characteristics among the individuals of the same species
2. selection process whereby organisms better adapted to their environment tend to survive and produce more
4. provides living things with everything that is necessary to survive
5. selection only allows the selected traits to be passed through successive generations
6. product of reproduction, produced by one or more parents.
8. the passing of traits
9. change in the heritable characteristics of biological populations over generations
10. means that each generation has more offspring than can be supported by the environment
