During a field study, a researcher observes a pollinating agent transferring pollen between two distinct, open flowers. Later, genetic analysis of the resulting seeds reveals that they are genetically identical to the parent plant. Which of the following types of pollination has occurred in this scenario?

Step-by-step solution

The observation that pollen transfer occurred between two distinct flowers via a pollinating agent indicates functional cross-pollination. This rules out normal autogamy (which occurs within the same flower) and cleistogamy (which occurs in closed flowers that do not open at all). The genetic analysis shows that the seeds are genetically identical to the parent plant. This means the pollen must have come from the same plant, ruling out xenogamy, which involves the transfer of pollen from a different plant and bring
