Information About Blue Eye Color

Partly because of the perception of beauty created by the media, from the rarity Therefore, blue eye color is more attractive to most people. But most people don’t know that blue eye color is compared to brown eye. disadvantages can be found. Whether your eyes are blue or brown; your eye color you got from your parents genetic inheritance determined and passed on from generation to generation. However, sometimes genetic variations or what our ancestors passed on genetic mutations can lead to surprising results.

Many people have misconceptions about the blue eye, driven by the knowledge they have gained from a high school biology course. However, genetics, which is a very broad branch of science about examining the factors inherited from our parents, such as our eye color, is as simple and It is not a monolithic science. There are many misconceptions that are known to be true, including eye color and eye color.

In order to fix some of these mistakes, blue eye color and we have compiled interesting information about people with blue eyes in our content.

How is blue eye color formed?

All eye colors iris in the colored part called ‘melanin’ It depends on the amount of a pigment called In other words, the perception that “blue and green eyes do not have pigment” is wrong. Compared to blue eyes, in brown eyes, in the posterior layer of the iris, sometimes even in the anterior layer, more melanin This causes the eye to absorb more light, making the eye color darker. Eyes that do not have melanin in the iris layers do not collect the light instead. distributes this reflects more blue light, making the color of the eye appear blue.

Where a child receives genetic information, such as eye color, is from their parents are chromosomes. Different genetic information from each parent also causes differences in the amount of melanin. There is also a special region on our chromosomes for determining eye color. In these special areas, it helps to determine the eye color. specific protein genes has. The higher the protein content, the higher the melanin intake. melanin uptake a single gene Although it is controlled by other genes, there are also effects. Therefore, parents with brown eyes can have children with blue eyes, and parents with blue eyes can have children with brown eyes.

So how true is the claim that ‘blue eye color can be unhealthy’?

Whether eye color is associated with certain health problems is still a subject of research by researchers, but in line with the information obtained to date, blue eye more prone to health problems is thought to be. The main reason for this is lack of melanin is seen. Diseases such as eye cancer, diabetes, macular degeneration and hearing loss are thought to be more common in people with blue eyes.

There is no certainty about these diseases that people with blue eyes need to worry about. In particular, you may not be able to make a connection between hearing loss and blue eye color. This information comes from the fact that people with light-colored eyes, who are only exposed to loud noises, suffer more pronounced hearing loss.

Interesting facts about blue eye color:

• Only 8% of the world’s population has blue eyes.
• People with blue eyes may have a common ancestor.
• In fact, we all had lighter eyes when we were born.
• Although there is brown pigment, there is no blue pigment.
• Blue eyes are more sensitive to light.
• Contrary to popular belief, blue eyes are not recessive.
• People with blue eyes have a higher risk of alcoholism.
• The perception that your child will have blue eyes just because you have blue eyes is wrong.

Only 8% of the world’s population has blue eyes.

If you have blue eyes, you are actually quite an elite group you are in. Most brown people have thought at least once, ‘I wish I had colored eyes’, and people with colored eyes are more attractive to most of us. Maybe it’s because you have such blue eyes is less available.

Also, people with blue eyes are the most North Europe seen in their countries. If Finland 89% It is the country with the highest number of blue-eyed people.

People with blue eyes may have a common ancestor.

According to a study conducted at the University of Copenhagen, blue eye color originated in the Black Sea Region about 10 thousand years ago. in a single person presumed to occur as a result of a genetic mutation is thought to have arisen. For this reason, it is thought that all blue-eyed people on Earth are descended from a genetic mutation, or ancestry, created by a single person.

In fact, we all had lighter eyes when we were born.

When babies are born, it is sometimes unpredictable what the eye color will be in the future because although blue eye color is one of the rarest eye colors, it is quite common in babies. The pigment of the human eye, when born because it is not the full amount Most babies are born with a lighter-than-normal eye color. Since the melanin hormone increases over time, it is found in most people as they grow. eye color darkens.

Although there is brown pigment, there is no blue pigment.

We mentioned that our eye color depends on the amount of melanin hormone in our iris layer. Blue eyes, color like brown eyes does not take from pigment. Just as the reason why the seas appear blue, from scattering the light The same is true for blue eyes.

Blue eyes are more sensitive to light.

Studies show that the melanin hormone in the iris protects the back of the eye from the sun. Protects from UV rays is being considered. Blue eyes; It also has less melanin than green and brown eyes. photophobia light sensitivity is more common.

Contrary to popular belief, blue eyes are not recessive.

One of the most common misconceptions is that blue eye is a recessive gene because it is found in a small number of people. However, the blue eye gene can also create eyes of other colors such as brown and green. It is an effective gene. In short, brown-eyed people can have blue-eyed children, too.

People with blue eyes have a higher risk of alcoholism.

According to a study in a science journal, people with blue eyes addiction to alcohol more likely to develop. In the study, the proportion of Europeans and Americans with blue eyes and alcoholism was higher compared to people with brown eyes. However, about this There is no scientific certainty.

The perception that your child will have blue eyes just because you have blue eyes is wrong.

We also mentioned that blue eyes are not recessive. Most of us in our biology classes recessive – dominant gene We learned about the event and that this event is dependent on 2 genes, but in fact, determining a child’s eye color is more complicated than that because eye color is not due to the effect of 2 genes. With the effect of 16 different genes being determined. In short, your child may have brown eyes even if you and your partner have blue eyes.
