Autogamy, or self-fertilization, refers to the fusion of two gametes that come from one individual. Autogamy is predominantly observed in the form of self-pollination, a reproductive mechanism employed by many flowering plants.

How does autogamy happen?

Autogamy, the production of gametes by the division of a single parent cell, is frequently found in unicellular organisms such as the protozoan Paramecium. These organisms, however, may also reproduce by means of conjugation, in which cross-fertilization is achieved by the exchange of genetic material…

How do plants prevent autogamy?

Please explain me how monoecious plants prevent autogamy but not geitonogamy and dioecious prevents both auto and geitonogamy. but they can undergo pollination with different flowers of the same plant (geitonogamy ). ... separate plant altogether so it prevents autogamy and geitonogamy.
