Definitions:

Sexual Isolation

A mechanism of evolutionary divergence where different species or populations can no longer interbreed due to behavioral or genetic barriers.

Gametic Isolation

A prezygotic barrier where gametes (egg and sperm) of different species are incompatible, preventing fertilization.

Mechanical Isolation

A form of reproductive barrier where differences in the size and shape of reproductive organs prevent mating between species.

Sympatric Speciation

The evolution of a new species within the same geographic region as the parental species. Compare with allopatric speciation.
