Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. Genetic variation is what makes us all unique, whether in terms of hair colour, skin colour or even the shape of our faces.1  Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation. Genetic variation is a result of subtle differences in our DNA. 2  Single nucleotide polymorphisms (SNPs, pronounced âsnipsâ) are the most common type of genetic variation amongst people. 3  Each single nucleotide polymorphism represents a difference in a single DNA base, A, C, G or T, in a personâs DNA.
