Apoximis or asexual seed formation
Apoximis is when a seed will be produced that can turn into a genetically identical plant.
Explanation;
Asexual reproduction is the type of production that results to offspring or organisms that are genetically identical to the parent plant. In plants, plants can reproduce asexually through vegetative reproduction or apomixis, without fertilization of gametes.
Apomixis is where some plants can produce seeds without fertilization. This occurs when an ovule or part of the ovary gives rise to a new seed.
