Apomixis is a method of asexual reproduction, in which neither myosis (separation of chromosomes) nor fertilisation (mixture of chromosomes) occur.
Apomictic species can thus produce seeds that are genetically identical to the mother plant, otherwise called clones.
Apomixis has several advantages in stable environments, as it allows a genetic formula adapted to a specific environment to be preserved from generation to generation. On the other hand, if the environment changes, this method of reproduction becomes disadvantageous, because it considerably slows down a plant's ability to evolve and adapt.
The dandelion (Taraxacum sp) is an apomictic species. This plant can therefore produce clones of itself. © luc.viatour CC by-sa
