Transferring pollen from one flower to the pistils of another flower is the process of cross-pollination. In nature, wind and insects both aid in pollination.
To create offspring with chosen features, such as colour or pest resistance, this process can also be carried out manually.
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.
The process of plants pollinating themselves is referred to as self-pollination.
