NEET2026Biology
Q.

Which one of the following types of pollination brings genetically different types of pollen grains to the stigma?

  1. A

    Autogamy

  2. B

    Xenogamy

  3. C

    Geitonogamy

  4. D

    Cleistogamy

Solution

Xenogamy is the transfer of pollen grains from the anther of one plant to the stigma of a genetically different plant. It is the only type of pollination that brings genetically distinct pollen grains to the stigma. Cleistogamous flowers are invariably autogamous.
