Gametic isolation refers to a set of circumstances whereby gametes are isolated or separated from their matches by a medium or distance. This description also refers indirectly to reproductive isolation, in which a gamete cannot interact with the gametes of another species.
Since size and shape are irrelevant to reproduction in plants, mechanical isolation is usually due to the use of a different pollinator for the plants. For instance, a plant that is structured so a bee can pollinate it will not be compatible with a flower that relies on hummingbirds to spread its pollen.hoto Credit: Getty/Christian Wilt. Mechanical isolation is probably the simplest concept that keeps individuals from being able to reproduce offspring with each other. Simply put, mechanical isolation is the incompatibility of sexual organs.
