Several studies have shown that the OCA2 locus is the major contributor to the human eye color variation. By linkage analysis of a large Danish family, we finemapped the blue eye color locus to a 166 Kbp region within the HERC2 gene.

2023年4月21日 · The research shows that the OCA2 gene codes play a key role in the production of melanin, the pigment that colors hair, skin, and eyes. Eiberg's theory is that a mutation occurred between...

2024年12月24日 · Blue eyes arise from a mutation in the gene OCA2, dialing down our body's ability to produce the melanin pigment for brown eyes. A mutated OCA2 gene was also detected in the ice-age boy.

2008年1月31日 · People with blue eyes have a single, common ancestor, according to new research. A team of scientists has tracked down a genetic mutation that leads to blue eyes. The mutation occurred...

2023年12月20日 · One gene that has been identified as playing a role in blue eye color is called OCA2. This gene influences the production of melanin, the pigment that gives color to our hair, skin, and eyes. Mutations in the OCA2 gene can result in a reduction of melanin production, leading to blue eyes.

2008年1月3日 · Several studies have shown that the OCA2 locus is the major contributor to the human eye color variation. By linkage analysis of a large Danish family, we finemapped the blue eye color locus to a 166 Kbp region within the HERC2 gene.

2023年12月20日 · The blue eye gene, also known as OCA2, is a key player in the development of blue eyes. Researchers have discovered that a specific variation in this gene interferes with the production of melanin, the pigment responsible for the brown color in the iris.

October 23, 2016 – New research shows that people with blue eyes have a single, common ancestor. Scientists have tracked down a genetic mutation which took place 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today.

2023年11月16日 · Did you know all blue-eyed people are almost descended from the same person? Alex Dainis breaks down the genetic variations that result in people having blue eyes. She explores the OCA2 gene and its role in shaping eye color evolution.

2023年3月11日 · We identified five new variants, rs74409036:A, rs78544415:T, rs72714116:T, rs191109490:C and rs551217952:C, to be the most promising candidates for explaining blue eye colour in individuals with the rs12913832:AA and AG genotype.
