Answer 1

Apomixis is a form of asexual reproduction in which an embryo is formed without meiosis and fusion of haploid gametes. It can take place through diploid sporophytic cells of the ovule or from an unfertilized egg (parthenogenesis) itself.

Significance:
Certain species of plants belonging to Asteraceae, and grasses exclusively use the phenomenon of apomixis for producing seeds.

Commercial applications of apomixis:

1. By apomixis, hybrid varieties of seeds can be produced, which will provide higher and better yield.

2. Apomixis prevents the loss of specific characteristics in the hybrid plants.

3. Apomixis is a cost-effective method of producing seeds.
