Question

State 3 disadvantages of self-pollination

Answer 1

Definition :

1. Self Pollination involves only one flower, making it a very basic type of pollination.
2. Self-pollination happens when pollen grain from the male portion of the flower (anther) lands directly on the stigma, which is the female component of the same flower, and fertilisation ensues.
3. Plants that pollinate themselves are known as self-pollinating plants.
4. Wheat, apricot, rice, peanut, and other self-pollinating plants are examples.

Disadvantages of self-pollination :

1. The seeds are in smaller quantities.
2. New plant varieties cannot be created. Because the endosperm is so little, the seeds produced are feeble.
3. The immunity of the offspring decreases if new characteristics are not introduced.
