Step 1

In plants, this means that the pollen comes from a flower on a different plant. Allogamy increases genetic diversity by combining the genetic material of two different individuals. Show more…

Key Concepts

Allogamy

A reproductive strategy in flowering plants where fertilization occurs between two different individuals. This cross-pollination increases genetic diversity by melding different gene pools, which is essential for the adaptive potential of a species.

Autogamy

A form of self-pollination where a flower’s own pollen fertilizes its ovules. This process ensures reproduction in the absence of pollinators or mates, though it limits genetic variation since the genetic material comes from a single flower.

Geitonogamy

A type of self-fertilization that occurs when pollen is transferred between different flowers on the same individual plant. Although it results in self-pollination and shares genetic drawbacks similar to autogamy, it often involves pollinators and can be considered an incidental outgrowth of the pollination process in plants with multiple flowers.

Allautogamy

A reproductive process involving self-fertilization through the transfer of pollen between separate flowers on the same plant that, while functionally similar to geitonogamy, is distinguished in some botanical texts. It emphasizes the concept where even though pollen may move externally among flowers, the resulting fertilization still involves genetically identical material.
