Definitions:

Parapatric Speciation

Parapatric speciation is the evolution of new species within a spatially extended population that still has some gene flow.

Allopatric Speciation

The evolution of new species after populations have been separated geographically, preventing gene flow between them.

Sympatric Speciation

The evolution of new species within a contiguous population that still has extensive gene flow.

Gametic Isolation

A type of prezygotic barrier where the gametes (egg and sperm) of two different species fail to unite or fertilize, preventing the formation of a zygote.
