Answer

Depending on the source of pollen grain, pollination can be classified into:

Autogamy: It is the transfer of pollen grain from anther to the stigma of the same flower.
Geitonogamy: lt is the transfer of pollen grains from anther of one flower to the stigma of another flower on the same plant. Geitonogamy is functionally cross-pollination involving pollinating agent, but genetically it is equivalent to autogamy since, the pollen grains come from the same plant.
Xenogamy: It is the transfer of Pollen grains from anther to the stigma of different plants of same species. It brings genetically different types of pollen grains to the stigma.
