Definitions:

Mechanical Isolation

A form of reproductive isolation where physical differences in the reproductive organs of different species prevent interbreeding.

Hybrid Sterility

A condition in hybrid animals or plants where they are unable to produce offspring due to genetic and chromosomal differences between the parents.

Hybrid Inviability

Hybrid inviability is a postzygotic barrier where hybrid offspring fail to survive to maturity, reducing the chances of genes being exchanged between different species.

Temporal Isolation

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