Explanation

Some plants are self-sterile, i.e. they are not fertilised when pollinated by the same variety of plant. In order to produce fruits, these plants require pollen from plants of a different genetic makeup. Some examples of self-incompatible plants are pineapples, navel oranges, and clementines.
