Q.What is Geitonogamy? Give example. OR What do you mean by reproductive health?

Geitonogamy is pollen transfer between two different flowers of the same plant — needs a pollinating agent like cross-pollination, but genetically it behaves like self-pollination.

Pollination is classified by the source of pollen into three types:

1. Autogamy — pollen is transferred within the same flower.
2. Geitonogamy — pollen is transferred from the anther of one flower to the stigma of a different flower borne on the SAME plant.
3. Xenogamy — pollen is transferred to the stigma of a flower on a genetically different plant.

Although geitonogamy requires a pollinating agent (insect, wind, etc.) and is morphologically similar to cross-pollination, both flowers involved belong to the same plant and carry an identical genotype, so genetically it is equivalent to autogamy — no new gene combination is introduced.
