Question

What is the definition of geitonogamy?

• A. Transfer of pollen from the anther of one flower to the stigma of another flower on the same plant.
• B. Transfer of pollen from the anther of one plant to the stigma of a flower on a different plant.
• C. Self-pollination where pollen from the same flower fertilizes the ovule.
• D. Cross-pollination between genetically distinct individuals.

Hint:

Geitonogamy can lead to inbreeding and reduced genetic diversity since it involves pollination within the same plant.

Answer 1

The Correct Option is A

Option 1 is correct

Geitonogamy describes self-pollination via pollen transfer between distinct flowers on the same plant. This contrasts with autogamy (pollen fertilizes ovules within the same flower) and allogamy (pollination between different plants).
