Charles Darwin |
|
|

Phenotype |
|
|
Genetic makeup of a trait |
Genotype |
|
|

|
|
Environment is unchanging and the "average is selected over the extreme. |
One of the three types of natural selection: Stabalizing |
|
|
Environment is changing, so one extreme is chosen over the average or the other extreme |
One of the three types of natural selection: Directional |
|
|
Occurs over a large range, or area, and the environment changes so that the two extremes are selected |
One of the tree types of natural selection: Disruptive |
