Answer 1

Self-pollination:

1. When the pollen grain of a flower pollinates the stigma of the same or stigma of another flower of the same plant, this process is called self-pollination.

3. It commonly occurs in genetically identical flowers.
4. It is the primary cause of inbreeding and reduces the gene pool.
5. This process can also occur when the flowers are closed because of the maturation of another and stigma at the same time.
6. It is of two types: autogamy and geitonogamy.

Types of self-pollination:

1. Autogamy is when pollen is transferred to the stigma of the same flower.
2. Geitonogamy is a process in which pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant.
