Incompatibility is the inability of gametes to fuse in genetically similar plants.
It is a controlled by genes with multiple alleles called S-alleles.
This phenomenon is also called intraspecific incompatibility. it involves many intricate mechanisms associated with stigmatic tissue and pollen grain.
When associated with genotype of stigmatic tissue, it is called sporophytic incompatibility and when associated with genotype of pollen, it is called gametophytic incompatibility.
