1 Genetic variation results in different forms, or alleles, of genes. 2  For example, if we look at eye colour, people with blue eyes have one allele of the gene for eye colour, whereas people with brown eyes will have a different allele of the gene. 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.
