Apomixis is the phenomenon of formation of seeds without fertilisation. These embryos are genetically identical to the parental plant.

(i) Vegetative propagation or reproduction is a form of asexual reproduction in plants, in which new organisms arise without production of seeds or spores.
(ii) Sexual reproduction involves formation of the male and female gametes, either by the same individual or by different individuals of the opposite sex. These gametes fuse to form the zygote which develops to form the new organism.
