Question

Which of the following is genetically self-pollinating but functionally cross-pollinating ?

Easy
Solution

Transfer of pollen grains from the anther to the stigma of another flower of the same plant is geitonogamy. Although geitonogamy is functionally cross-pollination involving a pollinating agent, genetically it is similar to autogamy since the pollen grains come from the same plant.
