The Genetics Of Hazel EyesThe human eyes are certainly fascinating and complex organs. Not only because they help us to see the natural world, but also the intrinsic beauty of the color of the iris. Take it upon yourself to really start looking at others in the eyes while speaking to them and observe the natural beauty and the various colors that eyes are. You will see everything from the brightest blue eyes to the deepest, darkest brown eyes. The spectrum of colors is certainly interesting!

What exactly are hazel eyes?

If you have hazel eyes, it basically means that your eyes change colors and can vary from green to a very light brown to gray. It oftentimes depends on the lighting that you are in. The characteristics of hazel eyes are quite interesting. Sometimes you will see a small ring around the iris and the iris will be greenish or bluish.

Various eye colors

If you take a look at a group of people, you will find the most common eye color will be brown. There will also be some blue eyes and a bunch of shades in between. The least common color will be green. The color will depend on how much of the pigment melanin is in the iris. If the eyes are brown, that means that there is a lot of melanin. If the eyes are green, there is a bit less melanin and if they are blue, there is no melanin.

The Genetics of Hazel Eyes

Have you ever known someone who had hazel eyes and you loved to look at their eyes to see if they would change colors on occasion? Hazel eyes are certainly interesting. The actual color looks a lot like the color of a hazelnut shell, or light or golden brown. There may be a little bit of yellow or green as well.

We are actually born with blue eyes but the pigment changes over time due to the amount of melanin in the eyes. Not that many people have hazel eyes, but no matter what color your eyes end up with has to do with what genes were passed down from your parents. Each parent has either a dominant or recessive gene that plays a part in whether you will have brown, blue, or hazel eyes.

There has not been a ton of research on the genetics of hazel eyes as of yet. According the Dr. Starr from Stanford University, you will get hazel eyes if the G and the M gene combine. With this being said, these combinations will result in hazel eyes: GGMM, GbMM, GGMm, and GbMm.

Some studies suggest that the color hazel is actually the color in between dark brown and brown and because of this on occasion the iris can appear multicolored. Some people with hazel eyes also have little specks of gold or amber color show when out in the sun. It is quite interesting to look deep into hazel eyes while out in the sunlight.

Doesn`t matter you have blue, green or brown eyes keep them healthy. Visit your eye doctor. Don`t be afraid of ophthalmic cabinet and special ophthalmic instruments. They are made to make you happy and your eyes healthy.
