Self Incompatibility is controlled by two genes is found in
A. Liliaceae
B. Cruciferae
C. Malvaceae
D. Gramineae
Answer: Option D
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.
