Solution

  1. Incompatibility refers to inability of certain gametes even from genetically similar plant species to fuse with each other.
  2. It is considered as the most prevalent and effective device to avoid inbreeding and outbreeding.
  3. Pollen pistil interaction is a dynamic process that involves pollen recognition followed by promotion or inhibition of the pollen. 
  4. Chemical substances released by the style act as a barrier.
  5. Typically the pollen belonging to the correct mating type germinates on stigma, develops a pollen tube, and brings about fertilization.
  6. The pollens belonging to the other mating type are discarded.

Thus, incompatibility is a natural barrier in the fusion of gametes.
