| 2929776098 | Hardy-Weinberg equilibrium | a population in which allele frequencies do not change over time such as in the moth population- genetic equilibrium | 4 | |
| 2929791211 | Hardy- Weinburg Principle | says that the genotype frequencies of a nonevolving population can be described by the expression p^2+2pq+q^2 | 5 | |
| 2929824034 | Hardy-Weinburg Principle | In the absence of external forces acting on a large, randomly-mating population: 1. The allele frequencies in the population will not change over time 2. The genotype frequencies will quickly reach an equilibrium where p= frq. A q=frq. a | 6 | |
| 2929852170 | no mutation no migration a large gene pool random mating no selection | The Hardy- Weinberg Principle only applies if there is... | 7 | |

| 2929889913 | gene flow | the movement of alleles between populations | 10 | |
| 2929893158 | genetic drift | the change in the allele frequencies of a gene pool due to chance events. removes individuals, and their genes, from a population at random- without regard for genotype of phenotype | 11 | |
| 2929912398 | reproductively isolated | incapable of interbreeding | 12 | |
| 2929949005 | Stabilizing selection | when an intermediate phenotype is the most adaptive for the given environmental conditons |  | 13 |
