INTERSTERILITY Meaning and
Definition
-
Intersterility is a term used in biology to describe the inability of two or more different species or groups of organisms to produce viable offspring when they interbreed. It is essentially a reproductive barrier that ensure the genetic isolation and distinctiveness of species. Intersterility arises due to various mechanisms that prevent successful fertilization, development, or viability of the hybrid offspring.
One common mechanism causing intersterility is known as gametic incompatibility, where the gametes (reproductive cells) of different species fail to recognize one another or are unable to fuse and form a zygote. This often occurs when the proteins or substances on the surface of the gametes are not compatible or are not recognized by each other's reproductive systems.
In some cases, intersterility may also be caused by postzygotic barriers, which affect the development and survival of the hybrid embryos or offspring. These barriers can include genetic incompatibilities that lead to abnormal development, reduced fertility, or inviability of the hybrid organisms. This prevents the successful establishment of a stable hybrid population.
Intersterility plays a crucial role in maintaining the integrity and diversity of species by preventing the merger of genetically distinct lineages. It is an essential factor in promoting speciation and the evolution of new species. The study of intersterility provides insights into the genetic, physiological, and ecological factors that influence reproductive compatibility and the evolution of reproductive isolation mechanisms.

Etymology of INTERSTERILITY
The word "intersterility" is derived from two components: "inter-" and "sterility".
1. "Inter-" is a prefix that comes from Latin and means "between" or "among". It is used to indicate the idea of interaction or mutual action between things.
2. "Sterility" refers to the state of being sterile, which is the inability to reproduce or produce offspring. It comes from the Latin word "sterilis", meaning "barren" or "infertile".
Combining these two components, "intersterility" refers to the inability of different species or varieties to produce viable offspring when they attempt to interbreed.
