Why are blue eyes so rare?
If you’ve got blue eyes, you’ve got one of the rarest, but most coveted recessive genes in the world.
The way blue eyes develop is even rarer than the eye color itself, however.
Scientists have discovered that a genetic mutation on the OCA2 gene changes the body’s pigment production, creating blue eyes..
What color eyes do most redheads have?
brownThat means both parents must carry a copy of the gene to produce a red-haired child and often the trait skips generations. Rarest of all are redheads with blue eyes. The majority have brown eyes or hazel or green shades.

How rare is strawberry blonde hair and blue eyes?

Before then, there were no blue eyes. “Originally, we all had brown eyes,” said Hans Eiberg from the Department of Cellular and Molecular Medicine at the University of Copenhagen.
What nationality has brown hair and blue eyes?
