Eye colour and genetic predisposition

A whole host of external features are determined in part by your DNA. One of these is your eye colour. We know, for example, that the so-called OCA2 gene is responsible for the difference between blue and brown eyes.

Eye colour and heredity

Scientists have not yet entirely resolved the question of which genes play precisely which role, but there is no doubt that heredity is one of the factors that determines your eye colour. You can therefore tell from your DNA how likely it is that your eyes will be a particular colour.
