WebInbreeding, also called selfing, is the union of gametes derived from a single individual. In flowering plants, inbreeding may occur either within a single flower, known as autogamy (infrafloral selfing) or between flowers derived from one individual, known as geitonogamy. (The genetic product of autogamy is identical with that of geitonogamy.) WebIn flowering plants, autogamy has the disadvantage of producing low genetic diversity in the species that use it as the predominant mode of reproduction. This leaves those species particularly susceptible to pathogens and viruses that can harm it.
