Definitions:

Postzygotic Barriers

Reproductive isolating mechanisms that occur after fertilization, preventing the development of viable or fertile offspring between different species.

Temporal Isolation

A mechanism of reproductive isolation in which different species breed at different times, preventing them from interbreeding.

Habitat Isolation

A prezygotic barrier where two species live in different habitats within the same area but do not meet, preventing them from mating.

Gametic Barriers

Reproductive obstacles that prevent gametes (sperm and egg) from two different species from fusing and creating a viable offspring.
