While green eyes are a beautiful and rare trait found in people across the globe, they are most concentrated in specific regions. According to the Gregarious Green Eye Facts from Eyesite, the largest concentration of green-eyed people is found in Ireland, Scotland, and Northern Europe.
Regions with High Green Eye Concentration
The presence of green eyes varies significantly by geography. The reference highlights that Ireland, Scotland, and Northern Europe are the areas with the highest prevalence of this eye colour. This does not mean these are the only places where people have green eyes, but rather where they are most commonly found.
Eye Colour Statistics in Ireland and Scotland
The data from Eyesite provides a notable statistic regarding the prevalence of lighter eye colours in certain areas of concentration. It states that in Ireland and Scotland, a remarkable 86% of people have either blue or green eyes. This high percentage underscores why these nations are identified as having a significant concentration of green-eyed individuals.
Genetic Factors in Eye Colour
Eye colour, including green, is determined by genetics. The reference mentions that 16 genes have been identified that contribute to eye colour. This demonstrates that it's a complex trait influenced by multiple genetic factors, not just one or two.
Here are the key facts based on the provided reference:
- Primary Concentration Areas: Ireland, Scotland, Northern Europe
