Question
Differentiate between geitonogamy and xenogamy (allogamy).
Advertisements
Solution
| Xenogamy (allogamy) | Geitonogamy | |
| 1. | Xenogamy is the transfer of pollen grains from the anther to the stigma of a different plant. | Geitonogamy is the transfer of pollen from one flower’s anther to another flower’s stigma. |
| 2. | This is the only type of pollination which during pollination brings genetically different types of pollen grains to the stigma. It is also known as allogamy. | Genetically, it is similar to autogamy, since the pollen grains come from the same plant. But it requires pollinating agents that help transfer the pollen from another flower onto the same plant. |
| 3. | It is cross-pollination. | It is self-pollination. |
