If pollen from a flower of a plant is used to pollinate another flower of the same plant, then
If pollen from a flower of a plant is used to pollinate another flower of the same plant, the process is called self pollination. Self pollination also occurs if the pollen of a flower is used to pollinate the same flower (as it is the same plant). Self pollination is not preferred by plants because it does not create diversity in characteristics. This is similar to having a single parent.
