It seems I am Scandinavian :)

No Dimi, blue eyes are primarily the result of a specific genetic mutation that reduces the amount of melanin—the pigment responsible for coloration—in the iris of the eye. The key genes involved are: OCA2: This gene, located on chromosome 15, produces a protein (P-protein) crucial for melanin production. A mutation in or near this gene reduces melanin in the iris, resulting in blue eyes instead of brown. HERC2: A regulatory region within this gene (specifically the SNP rs12913832) controls the expression of OCA2. The mutated version of this region significantly reduces melanin production, leading to blue eyes. This mutation behaves as a recessive trait, meaning both parents must pass on the variant for a child to have blue eyes. And other stuff on ChatGPT. :D

This means that the other regions doesnt have people with blue eyes?

In Serbiae have people with blue eyes
