(1) A type of reproduction in plants where the usual sexual reproduction is replaced by asexual means that does not involve meiosis and syngamy.
(2) Seed production without involving fertilization.
(3) The formation of a new sporophyte but not involving fertilization.
This form of reproduction has evolved in ferns, dandelions and other flowering plants. In flowering plants, it occurs in two forms:
- gametophytic apomixis
- adventitious embryony
Seeds produced by apomixis are genetically similar to the parent plant.
