The Science Behind Blue Eyes In Melanesians: Famous Examples

Scientists have found that people with blue eyes often have a specific genetic variation in the oca2 gene. This variation reduces the production of melanin in the iris,. The mutation responsible for blue eyes likely occurred on a single allele initially. This means that the original ancestor carrying the mutation may not have had blue eyes themselves but was. Blue eyes, for example, are the result of a mutation in the oca2 gene that reduces the amount of melanin produced in the iris.

Blue eyes, for example, are the result of a mutation in the oca2 gene that reduces the amount of melanin produced in the iris. This reduction in melanin leads to less.

This reduction in melanin leads to less.
