The pollination which involves the transfer of pollen grain from the anther to the stigma of another flower of the same plant is known as-
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Geitonogamy
Option (1) Geitonogamy — Correct. Both flowers are on one plant, so the pollen carries the same genes as the stigma it lands on. An insect or the wind is still needed to carry it between the flowers. So it works like cross-pollination but gives no new combination of genes.
Option (2) Xenogamy — Incorrect. Xenogamy is the transfer of pollen to the stigma of a flower on a different plant. It is the only type that brings genetically different pollen.
Option (3) Cleistogamy — Incorrect. Cleistogamous flowers never open, as in Viola, Oxalis and Commelina. The pollen reaches the stigma of the same flower.
Option (4) Dichogamy — Incorrect. Dichogamy is not a type of pollination. It is a condition in which the anther and the stigma of a flower mature at different times. It is one of the devices that prevent self-pollination.
