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.
For Gradualism, changes in species is slow and gradual, occurring in small periodic changes in the gene pool, whereas for Punctuated Equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non-change
