How Are Grey Eyes Inherited?

Grey eyes, like other eye colors, are determined by genetics. The color of our eyes is influenced by the amount and type of pigments in the iris. In the case of grey eyes, the color is a result of a lack of pigmentation combined with scattering of light.

🧬 Genetics of Grey Eyes

The inheritance of eye color involves complex interactions between multiple genes. While the specifics are intricate, it's generally understood that variations in the OCA2 and HERC2 genes play a crucial role in determining eye color.

Experts are still discussing how grey eyes are inherited, but most evidence suggests it involves a mix of dominant and recessive genes influencing their development.

Grey Eyes vs Blue Eyes

Grey eyes are often mistaken for blue eyes, and it's no surprise given their similar appearance. However, these two eye colors have distinct characteristics.

🆚 Pigmentation Differences

Blue eyes have a blue hue due to the Rayleigh scattering of light, similar to how the sky appears blue. In contrast, grey eyes lack this intense scattering, resulting in a more muted, subtle shade.

🆚 Versatility in Appearance

Since the front layer of the iris has less melanin than the back layer, grey eyes change based on lighting and surroundings. They can appear blue, green, or even have a touch of hazel, contributing to their mystique and attractiveness.
