What is geitonogamy?
Options
- ATransfer of pollen grains from the anther to the stigma of another flower of the same plant
- BTransfer of pollen grains from anther to stigma within the same flower
- CTransfer of pollen grains from anther to stigma of a different plant
- DTransfer of pollen grains by water
Correct answer
A. Transfer of pollen grains from the anther to the stigma of another flower of the same plant
Step-by-step solution
Geitonogamy – Transfer of pollen grains from the anther to the stigma of another flower of the same plant. Although geitonogamy is functionally cross-pollination involving apollinating agent, genetically it is similar to autogamy since the pollen grains come from the same plant. Xenogamy – Transfer of pollen grains from anther to the stigma of a different plant. This is the only type of pollination which during pollination brings genetically different types of pollen grains to the stigma.
