Solution (By Examveda Team)

Self Incompatibility is controlled by two genes found in Gramineae.
Self-incompatibility (SI) is defined as the inability to produce zygotes after self-pollination in a fertile hermaphrodite plant, which has stamens and pistils in the same flower. This structural organization of the hermaphrodite flower increases the risk of self-pollination, leading to low genetic diversity.
SI is controlled by genes at the S-locus. The S-LOCUS RECEPTOR KINASE (SRK) gene encodes a serine/threonine kinase localized in the plasma membrane of the stigma epidermis.
