| 6049580690 | Evolution | A change in allele frequencies in a population over many generations. | 0 | |
| 6049580691 | Allele | the different versions of a gene | 1 | |
| 6049580692 | Hardy-Weinberg Equation | p² + 2pq + q² =1 |  | 2 |
| 6049580693 | Gene flow | Movement of alleles into or out of a population due to the migration of individuals to or from the population. It INCREASES diversity. | 3 | |
| 6049580694 | Mutations | Random errors in gene replication that lead to a change in the sequence of nucleotides. The source of all genetic diversity. | 4 | |
| 6049580695 | Nonrandom mating | Individuals choose their mates for a specific reason. | 5 | |
| 6049580696 | Natural Selection | A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits. | 6 | |
| 6049580697 | Genetic Drift | A change in the gene pool of a population due to chance. It LIMITS diversity. | 7 | |
| 6049580698 | Bottleneck Effect | When a population has been dramatically reduced, and the gene pool is no longer reflective of the original population's. It LIMITS diversity. | 8 | |
| 6049580699 | The Founder Effect | When a small population breaks away from a larger one to colonize a new area, it is most likely not genetically representative of the original larger population. | 9 | |
| 6049580700 | Gene Pool | All of the alleles in all the individuals that make up a population | 10 | |
| 6049580701 | Heterozygous | An organism that has two different alleles for a trait | 11 | |
| 6049580702 | Homozygous | Having two identical alleles for a particular gene | 12 | |
| 6049580703 | Linnaeus | Invented binomial nomenclature | 13 | |
| 6049580704 | Lamarck | inheritance of acquired characteristics | 14 | |
| 6049580705 | Darwin | English natural scientist who formulated a theory of evolution by natural selection | 15 | |
| 6049580706 | Stabilizing Selection | Natural selection in which intermediate phenotypes survive or reproduce more successfully than do extreme phenotypes. | 16 | |
| 6049580707 | Disruptive Selection | Increases the extreme types in a population at the expense of intermediate forms. Over great lengths of time, disruptive selection may result in the formation of two new species. | 17 | |
| 6049580708 | Directional Selection | Natural selection in which individuals at one end of the phenotypic range survive or reproduce more successfully than do other individuals. | 18 | |
| 6049580709 | Artificial Selection | Humans breed plants and animals by seeking individual with desired traits as breeding stock. | 19 | |
| 6049580710 | Fitness | How well an organism can survive and reproduce in its environment | 20 | |
| 6049580711 | Adaptive evolution | An evolutionary process that is directed by natural selection, which makes a population better adapted to live in an environment. | 21 | |
| 6049580712 | Allopatric Speciation | the evolution of new species through the process of geographic isolation into two separate environments | 22 | |
| 6049580713 | Sympatric Speciation | occurs when a species evolves into a new species in an area without a geographic barrier | 23 | |
| 6049580714 | Continental Drift | Wegener's idea that the continents slowly moved over Earth's surface, leading to allopatric speciation | 24 | |
| 6049580715 | Diploid | having two sets of chromosomes | 25 | |
| 6049580716 | Haploid | Cell that has half the number of chromosomes as body cells | 26 | |
| 6049580717 | Heterozygote advantage | greater reproductive success of heterozygous individuals compared with homozygotes; tends to preserve variation in a gene pool | 27 | |
| 6049580718 | Homologous Structures | Structures that come from the same ancestor...have a common origin and reflect a common ancestry. | 28 | |
| 6049580719 | Analogous Structures | Similar in function but not structure, like the wing of a bat and the wing of a butterfly. | 29 | |
| 6049580720 | Convergent Evolution | The process by which unrelated species become more similar as they adapt to the same kind of environment | 30 | |
| 7565139491 | Prezygotic barriers | Prevent mating between different species by blocking the zygote from forming | 31 | |
| 7565159385 | Postzygotic barriers | Prevent the hybrid zygote from developing into a viable, fertile adult | 32 |
