Bees may pick up pollen of one species on a certain place on their bodies; if this area does not come into contact with the receptive structures of the flowers of another plant species, the pollen is not transferred. This is an example of .

Mechanical Isolation

Explanation:

Mechanical isolation can be defined as a process whereby sexual reproduction between two different species is impossible.

In order for mechanical isolation to work, mechanical hindrances or barriers are created in other to prevent two different species from copulating.

An example is when Bees may pick up pollen of one species on a certain place on their bodies; if this area does not come into contact with the receptive structures of the flowers of another plant species, the pollen is not transferred.

In this example, the mechanical barrier is the certain place on the body of the bee that does not come in contact with the receptive structures of the flowers of another plant species due to its shape.
