Apomixis is

Explanation

Production of seeds without fertilisation is called Apomixis. It is a form of asexual Reproduction that mimics sexual reproduction. In some species, the diploid egg cell is formed, with out Meiosis and develops into embryo without fertilization. It is an assured reproduction in the absence of pollinators such as in extreme environments.
Importance :
1) Apomixis do not involve meiosis. Hence reggregation and recombination of chromosomes, do not occur. Thus Apomixis help in preserving desirable characters for Indefinite periods.
2) Apomixis, simplified commercial hybrid seed production.
