  • Self-incompatibility or intraspecific incompatibility is a well-designed genetic mechanism by which certain plants recognize and reject their own pollen thus forcing outbreeding. 
  • It is defined as “the inability of the plant producing functional gametes to set seeds upon self-pollination”.
  • Gametophytic self-incompatibility is due to the genotype of pollen, for example, Liliaceae, Solanaceae, Poaceae.
  • Sporophytic self-incompatibility is due to the genotype of sporophytic or stigmatic tissues, for example, Brassicaceae.

Hence, the correct answer is option b.
