In order for natural selection to operate on a trait, the trait must possess heritable variation and must confer an advantage in the competition for resources. If one of these requirements does not occur, then the trait does not experience natural selection.

The difference between the two is that natural selection occurs in nature, but selective breeding only occurs when humans intervene. Selective breeding is a process where we choose the characteristics we want in an animal.
