Show Answer
Answer:
Correct Answer: A
Solution:
- Geitonogamy is functionally cross pollination but genetically it is autogamy because in geitonogamy the pollens come from the same plant. Pollens are being transferred to the stigma of one flower to another flower of/on the same plant, which is genetically same. Therefore, geitonogamy is a cross pollination phenomenon but, is equivalent to autogamy genetically.
