How Rare Are Brown Hazel Eyes?

Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world’s population. Hazel/amber is the next rarest of these. Gray: The Rarest Eye Color.

Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world’s population. Hazel/amber is the next rarest of these. Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide.
Why do hazel eyes look brown?
People often confuse hazel with brown eyes because of the nearly similar hues. Although rare, hazel eyes have the second-highest concentration of melanin, making them appear light brown in some environments. Typically, hazel eyes take the color of a hazelnut — a mixture of green and brown. But color combinations of other shades like gold, amber, and blue also occur. The varying shades scatter light differently in various conditions. As a result, hazel eyes tend to swing between pure green and pure brown hues as the lighting conditions change.
What genes is hazel eyes?
Gene combinations and eye color – Before launching into this, we need to remember one more thing. We have two copies of most of our genes – one from mom and one from dad. What this means is that there are actually a number of ways of combining genes to end up with various eye colors. For brown, green, and blue eyes, the possibilities using BEY2 and GEY are:
|BB G b||Brown|
|B b bb||Brown|
|B b G b||Brown|
|B b GG||Brown|
|bb G b||Green|
Now imagine a modifier gene that can give you hazel eyes by having GEY make more melanin. This gene comes in two flavors – M increases the amount of melanin GEY makes and m has no effect. As you can see, it is possible to have brown eyes and have a B and a b version of the BEY2 gene.
- Or green eyes and have a G and a b version of GEY,
- These people are carriers for blue eyes.
- OK, so to have hazel eyes you need a G from the GEY gene and an M from our modifier gene.
- M would not give hazel eyes with b,
- Why? Because b is really a broken version of G – b makes so little melanin because it doesn’t work.
M can’t fix a gene – it can only affect how much melanin a working GEY gene makes. So what are the genetic combinations that give various eye colors using M ? To simplify things, we’ll ignore BEY2 and just concentrate on green, blue, and hazel.
|G b MM||Hazel|
|GG M m||Hazel|
|G b M m||Hazel|
|G b mm||Green|
|bb M m||Blue|
Are hazel eyes Golden?
Hazel eyes are a bit of a mystery. For starters, people describe this beautiful eye color in many different ways. Some say it looks like hazelnut, while others call it golden or brownish green. One of the reasons it’s so hard to describe hazel-colored eyes is that the hue itself seems to change, depending on what you wear and the type of lighting you are in.
Why do hazel eyes look brown?
Hazel eyes vs green eyes – Hazel and green eyes both get their colors from Rayleigh scattering, but it’s the way the light is scattered in the iris combined with the levels of melanin that distinguishes one from another. Hazel eyes have a substantial amount of melanin towards the center—or in some cases the outer region—of their irises, giving them their signature green-brown appearance.
How do you tell if my eyes are brown or hazel?
Gluten, Dairy, Sugar Free Recipes, Interviews and Health Articles The more melanin in the iris of your eyes, the darker they are. Both hazel and brown eyes have a normal level of melanin presence at the back layer. At the front layer, brown eyes have a heavy melanin presence. At this layer with hazel eyes, the presence of green is higher than the presence of brown, |
