Helps maintain genetic variability in a population

Sefl incompatibility is a mechanisms in plants that help in preventing inbreeding and allows outcrossing. This is controlled genetically by one or more multi allelic loci and usually relies on the series of complex cellular process and interaction between pollen and the pistil. There are various types of self incompatibility used by angiosperm. In this process autogamy is prevented and allogamy is produced.

The proton has a positive charge while the neutron has no charge they both make up the nucleus of the atom while the elections have a negative charge and surround the nucleus of the atom. the protons and electrons are used to calculate the atom's mass whereas the neutrons don't affect the mass
