ENDOMIXIS Meaning and
Definition
-
Endomixis is a biological process that refers to the fusion of gametes within the same individual or organism. It is a type of sexual reproduction where two gametes, usually from the same parent individual, come together to form a zygote.
In endomixis, unlike in most forms of sexual reproduction, the two gametes are genetically identical or nearly identical since they originate from the same individual. This process is commonly observed in certain plant species, especially those that are hermaphroditic and capable of self-fertilization.
Endomixis plays a significant role in maintaining genetic diversity within a population, as it introduces a certain level of variability in the offspring even when the same individual is involved in reproduction. It allows for the recombination of alleles and genetic material, leading to the creation of genetically unique individuals.
The term "endomixis" derives from the combination of "endo," meaning within or inside, and "mixis," referring to the process of mixing or merging. In this case, it signifies the fusion of gametes within the same individual.
Overall, endomixis is an essential biological process that enables self-fertilization and the production of genetically diverse offspring within a population, contributing to the overall genetic adaptability and survival of a species.
Etymology of ENDOMIXIS
The word endomixis is derived from the Greek roots endo, which means within, and mixis, meaning mixture or combining. The combination of these roots gives the word its meaning as the process of genetic recombination or mixing of genetic material that occurs within an individual organism.
