where does the blue eye gene come from
Eye color In humans, the inheritance pattern followed by blue eyes is considered similar to that of a recessive trait (in general, eye color inheritance is considered a polygenic trait, meaning that it is controlled by the interactions of several genes, not just one).[14] In 2008, new research tracked down a single genetic mutation that leads to blue eyes. "Originally, we all had brown eyes," said Eiberg.[35] Eiberg and colleagues suggested in a study published in Human Genetics that a mutation in the 86th intron of the HERC2 gene, which is hypothesized to interact with the OCA2 gene promoter, reduced expression of OCA2 with subsequent reduction in melanin production.[36] The authors suggest that the mutation may have arisen in the northwestern part of the Black Sea region, but add that it is "difficult to calculate the age of the mutation."[35][36][37]
Don't It Make My Brown Eyes Blue "Don't It Make My Brown Eyes Blue" is a song written by Richard Leigh, and recorded by American country music singer Crystal Gayle. It was released in March 1977 as the first single from Gayle's album We Must Believe in Magic. Despite the title, Gayle herself has blue eyes.
