Genetic variation refers to the differences in genes among individuals and between populations. These variations are caused by mutations, genetic recombination, and alterations in chromosome structure or number.

From the given options:

1. Weight: This is not purely a genetic variation as it is influenced by both genetic factors and environmental factors such as diet and exercise.

2. Regional accent: This is not a genetic variation. Accents are learned and influenced by the environment, not determined by genes.

3. Natural eye colour: This is an example of genetic variation. Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin.

4. Scars: These are not genetic variations. Scars are the result of physical injury and the body's attempt to heal itself, not a trait passed down through genes.

So, out of the given options, only natural eye colour is an example of genetic variation.
