2. an animal establishes a home in a habitat because it has resources it can utilize or because the habitat is ideal for them.
4. p2+2pq+q2=1
7. an organism's ability to pass its genetic material to its offspring
8. A chromosome that is similar in physical attributes and genetic information to another chromosome
10. any difference between cells, individual organisms, or groups of organisms of any species
13. hide or disguise the presence of (a person, animal, or object) by means of camouflage.
14. the process through which populations of living organisms adapt and change.
18. a form of natural selection wherein individuals with moderate or average phenotypes are more fit
19. substance or object in the environment required by an organism for normal growth, maintenance, and reproduction.
20. the combination of all the genes (including alleles) present in a reproducing

1. a theory that changes of organic life and of the Earth itself occur through gradual increments,
3. the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations
5. the change in frequency of an existing gene variant in the population due to random chance
6. a particular section, group, or type of people or animals living in an area or country.
9. occurs when both extreme traits are favored in an environment.
11. the close external resemblance of an animal or plant (or part of one) to another animal, plant, or inanimate object.
12. the evolutionary process whereby an organism becomes better able to live in its habitat or habitats.
15. the relocation or process of people leaving one country to reside in another
16. when more extreme phenotypes (or genotypes) within a population have a fitness advantage over intermediate individuals.
17. the presence of differences in sequences of genes between individual organisms of a species.
