Re-created by Dedric Bush & Nacey Fernandez
Important Terms
Evolution
Gene flow
Genetic Drift
non random Mating
Mutations
Natural Selection
Artificial Selection
Evolution
[ev-uh-loo-shun]
noun
----------------------------------------------------
Change in the gene pool of a population from generation to generation by such processes as mutation, natural selection, and genetic drift.
Non-Random Mating
The practice of two individuals mating based on appearance and/or personality, instead of random selection.
The process by which traits are found more or less common in an environment based on how often they are used. It is considered a key mechanism of evolution.
Natural Selection
Gene flow
When new individuals immigrate to and/or from an area, the frequency of occurrence of the genes will change.
The Five Fingers of Evolution
Genetic drift
The change in the frequency of a gene variant in a population because of random sampling of organisms.
Mutations
The permanent alteration in a DNA sequence that makes up a gene, such that the frequency differs from what is found in other people.
Artificial Selection
The breeding of certain organisms to produce a certain trait.
examples
-farmers breeding larger animals to produce larger animals
-humans genetically modifying plants' DNA
