Question
Differentiate between geitonogamy and xenogamy in plants. Which one between the two will lead to inbreeding depression and why?
✓
Answer
| S. No | Geitonogamy | Xenogamy |
| (i) | It is transfer of pollen grains from the anther to the stigma of another flower of same plant. | It is transfer of pollen grains from the anther to the stigma of a different plant. |
| (ii) | The pollen grains are genetically similar to the plant. | The pollen grains are genetically different from the plant. |
Geitonogamy will lead to inbreeding depression because the pollen grains are genetically similar, which results in inbreeding. Continued inbreeding will thus reduce fertility and productivity.
