Apomixis

(重定向自A****spermy)
Vegetative apomixis in Poa bulbosa; bulbils form instead of flowers
Caribbean Agave producing plantlets on the old flower stem.

In botany, apomixis was defined by Hans Winkler as replacement of the normal sexual reproduction by ****ual reproduction, without fertilization. Its etymology is Greek for "away from" + "mixing". This definition notably does not mention meiosis. Thus "normal ****ual reproduction" of plants, such as propagation from cuttings or leaves, has never been considered to be apomixis, but replacement of the seed by a plantlet or replacement of the flower by bulbils are types of apomixis. Apomictically produced offspring are genetically identical to the parent plant.
