Correct Answer:
xenogamy
Explanation:
Geitonogamy is a type of pollination in which pollen grains of one flower are transferred to the stigma of another flower belonging to either the same plant or genetically similar plant. Autogamy is a type of self pollination in which an intersexual or perfect flower is pollinated by its own pollen. Xenogamy is the transfer of pollen grains from the anther of one flower to the stigma of a genetically different flower. Xenogamy is responsible for heterozygosity. Allogamy is a type of cross polllination in flowering plants.
