NEET BIOLOGY

Detailed explanation-1: -Final Answer: Geitonogamy requires pollinators but is genetically similar to autogamy.

Detailed explanation-2: -The pollen grains are not transferred to a different plant. Hence, due to this there is no genetic variation in the offspring, and identical to the parent plant. Hence, geitonogamy can be called autogamy as the pollen grains come from the same plant and is genetically similar to autogamy.

Detailed explanation-3: -Geitonogamy is functionally cross-pollination involving a pollinating agent, but genetically it is similar to autogamy since the pollen grains come from the same plant. In a process known as geitonogamy, pollen grains are transferred from one bloom’s anther to the stigma of another flower on the same plant.

Detailed explanation-4: -Geitonogamy and Xenogamy refer to different types of cross-pollination. Geitonogamy refers to the transfer of pollen grains to the stigma of the same plant. Xenogamy refers to the transfer of pollen grains to the stigma of a different plant.

Detailed explanation-5: -Solution : Difference : In geitonogamy, transfer of pollen grains from anther to the stigam of another flower of the same plant while in xenogamy, transfer of pollen grains grom another to the stigma of a different plant. <br> Similarity : Both help in pollination by transfer of pollen grains to the stigma.
