Mutation resulting from changes in a single gene is called Gene mutation.
- A gene variation is an alteration to a gene's DNA sequence that takes place throughout time.
- Gene variation is regarded to be a more accurate word for this sort of genetic change than gene mutation since changes in DNA do not necessarily result in illness.
- Gene variations can be acquired from one's parents or develop naturally over time.
- Inheritable variations are present in almost all of a person's cells throughout their lifetime and are transferred from parent to kid.
- Non-inherited variations appear at some point in a person's life and are found in just a subset of the body's cells, not all of them.
- Non-inherited variations are sometimes referred to as somatic variants since they generally arise in somatic cells.
So we can conclude that a gene variation is a change in a gene's DNA sequence that occurs over time; it is thought to be a more appropriate term for this type of genetic change than gene mutation because DNA variations do not always cause disease, it also resulting from changes in a single gene.
