What are the types of pollination? Which among them is more advantageous? Why?

- Pollination is of two types – Self-pollination and cross pollination.

Self-pollination: - In self-pollination, pollen from anther of one pollination lands on the stigma of same flower. It is also known as autogamy. E.g. Wheat, barley etc.



Cross- pollination: - In cross-pollination pollen from anther of one flower lands on the stigma of other flower by the means of water or animals or wind. It is also known as allogamy. E.g. grasses etc.


Cross pollination is more advantageous because in this type of pollination there are chances of formation of new varieties of seeds and more viable seeds. Along with this there are chances that bad characters of the parent plant may get eliminated and won’t pass to next generation.
