Why are some seeds referred to as apomictic seeds? Mention one advantage and one disadvantage to a farmer who uses them.

Apomixis is the asexual production of seeds so that apomictic seeds are clones of the mother plant. The production of viable seeds without pollination or fertilization is called apomixis. These seeds are produced from flowers, just as regular seeds, but no pollen is involved. For example, Mangosteen produces apomictic seeds within the fruit. Even dandelion produces many apomictic seeds. An advantage of apomixis is that it would drastically reduce the cost of hybrid production, so that plant breeders produce new varieties of seeds more quickly and more cheaply. A disadvantage of apomictic seeds is that it reduces genetic diversity from parent to offspring plants due to lack of variations in asexual reproduction.
