Self-fertilization
In 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. In addition, the foraminiferans that use autogamy have shown to produce substantially smaller progeny as a result. This indicates that since it is generally an emergency survival mechanism for unicellular species, the … WebThe term selfing that is often used as a synonym, is not limited to self-pollination, but also applies to other types of self-fertilization.
