APOMICTIC Meaning and
Definition
-
Apomictic refers to a form of reproduction in plants where seeds are produced without the process of fertilization, resulting in offspring that are genetically identical to the parent plant. This type of asexual reproduction can occur in various plant species and is characterized by the development of embryos from unfertilized eggs within the ovules.
In apomictic plants, the production of seeds bypasses the usual sexual reproductive mechanisms involved in the union of male and female gametes. Instead, the ovule undergoes a process known as diplospory or apospory, where a diploid female gamete is formed directly within the ovary or nearby tissues. This gamete then develops into an embryo, giving rise to the next generation without any contribution from male gametes.
Apomictic reproduction allows plants to bypass the genetic recombination that occurs during sexual reproduction, ensuring the propagation of traits identical to the parent plant. This can be advantageous in certain circumstances, such as in habitats with a lack of suitable pollinators or when a plant possesses desirable characteristics that need to be preserved.
Apomixis can also refer to the production of seeds that are genetically identical to the parent plant but may result from other mechanisms like hybridization or chromosome duplication. Although apomixis is primarily found in plants, it can occur in some animals and fungi as well.

Etymology of APOMICTIC
The word "apomictic" is derived from the Greek words "apo" meaning "away" or "off" and "miktos" meaning "mixed" or "mingled". The term was coined in the early 20th century by E. Sinnott, an American geneticist, to describe a specific type of asexual reproduction in plants where seeds are produced without fertilization.
