- Autogamy is a type of self-pollination in which pollen grains are transferred from the anther to the stigma of the same flower123. It is a form of inbreeding that leads to homozygosity2. Autogamy is mostly found in flowering plants, especially those with chasmogamous flowers14. Some protists also use autogamy as a reproductive mechanism in stressful environments4. Autogamy is different from geitonogamy, which is the transfer of pollen between different flowers on the same plant3.

biologysir.com/autogamy-pollination-definition-and …Autogamy is predominantly observed in the form of self-pollination, a reproductive mechanism employed by many flowering plants. However, species of protists have also been observed using autogamy as a means of reproduction. Flowering plants engage in autogamy regularly, while the protists that engage in autogamy only do so in stressful environments.
