Absence of genetic mechanisms which prevent self-fertilizationSelf-compatibility (SC) is the absence of genetic mechanisms which prevent self-fertilization resulting in plants that can reproduce successfully via both self-pollen and pollen from other individuals. Approximately one half of angiosperm species are SI, [1] the remainder being SC.en.wikipedia.org/wiki/Self-incompatibility- See more

Self-compatibility (SC) is the absence of genetic mechanisms which prevent self-fertilization resulting in plants that can reproduce successfully via both self-pollen and pollen from other individuals. Approximately one half of angiosperm species are SI, the remainder being SC. Mutations that disable SI (resulting in … See more
Self-incompatibility (SI) is a general name for several genetic mechanisms that prevent self-fertilization in sexually reproducing organisms, and thus encourage outcrossing and allogamy. It is contrasted with … See more
These mechanisms have received only limited attention in scientific research. Therefore, they are still poorly understood.

In incompatible ("self") tubes the interaction of, for example, the S 1 SCF with the S 1 S-RNase blocks its degradation so the RNAs of the pollen tube are destroyed and growth is halted. An entirely-different mechanism of gametophytic self …
Distyly - Wikipedia
A supergene, called the self-incompatibility (or S-) locus, is responsible for the occurrence of distyly. The S-locus is composed of three tightly linked genes (S-genes) which segregate as a single unit.
Traditionally it was hypothesized that one S-gene controls all female aspects of distyly, one gene that controls the male morphological aspects, and one gene that determines the male mating type. …Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 9 mins
