Blue, Green or Brown – What Determines Your Baby Eye Color

Baby eye color preoccupies many parents. Some prefer their child will have blue eyes. Others wish for brown, hazel or green. At present, around 17% of the population in the United State has blue eyes compared to the 1950s when the figure was 35%. Worldwide, less than 10% of the population has blue eyes.

The majority of the babies are born with blue eyes. This is because the blue color, in fact, indicates lack of color or pigment. By the time the baby reaches 6 – 12 months, the cells in her iris are filled with the color or pigment she has inherited from her parents and that color becomes permanent for years to come.

So, genetics fills a major role in determining your baby eye color. If the parents’ eyes are brown, their children will most likely inherit the brown pigment from them. The brown color is dominant. Even if one parent has brown eyes and the other has blue eyes, the chances are greater for a child with brown eyes.

Nevertheless, there are cases in which both parents have brown eyes and their child has blue or green eyes as a result of autosomal recessive inheritance. In other words, both parents have a recessive (passive) gene for bright colored eyes and they pass it on to their offspring.

Geographic factors

Geography also plays an important role in determining baby eye color. In the last 15,000 – 20,000 years, most blue-eyed people have inhabited the northern regions of the planet and they gave birth the babies with blue eyes. In the more southern regions of the Middle East and Africa, brown eyes were much more widespread and so babies were born with darker eyes.

The reason for this geographic division lies in sensitivity to light. Brown eyes contain the pigment melanin, which can absorb ultraviolet radiation. This protects the eyes from harmful sun rays. In the southern regions of the planet, the sun’s radiation is much stronger compared to the north.

To sum up, your baby eye color is nothing more than a pigment passed on to her as part of the hereditary process that is responsible for other traits as well. It says nothing about your child’s character, temperament, intelligence or any other talent or skill she will acquire later on in life. If you are disappointed with one color or another, try to remember that.
