Analyzing Eye Color Genetics Chart and What You Need to Know

What is “Eye Color Genetics Chart ?” This chart is mainly used to predict the eye colors of your baby. Parents often wonder what color of eyes their child will have; and according to researchers who’ve studies ‘eye color’ field for over a century, they claimed eye color followed simple Mendelian genetic rules – brown eyes were dominant and blue eyes were recessive. If both parents have blue eyes, their baby would inevitably inherit their eye color. But it’s not that simple, keep learning here:

Recently, scientists have come to realize that eye color is a polygenic trait that means it’s influenced by more than one gene. It is possible to estimate the probability of a baby having a particular eye color, while enough factors influence this trait that the precise shade of eyes a baby will have is still a mystery that can’t be solved until he (she) grows. You can’t use Eye Color Predictor to simply determine the eye colors of grandparents and parents and calculate the odds of what color a baby’s eyes will have. In fact, a kid who’s born in a family with many generations of brown-eyed individuals might end up with green or blue eyes.

Human eye color genetics are complex as there are many variations of eye color among people. These variations occur since more than one gene controls the expression of the trait; actually, over 15 different genes have been associated with eye color inheritance. For instance, when saying a person who has brown eyes, you may overlook that there are various shades of brown – that’s all a result of a complex pattern of inheritance.

Put it simply, this activity will focus mainly on three common alleles that affect the basic shade of eye color: brown, blue, and green eyes. The alleles are located on separate chromosomes so they tend to independently assort during the creation of gametes. Each person has four total alleles that help determining the eye color – the brown allele is always dominant over both green and blue alleles, and the green allele is dominant over blue allele. A person’s eye color could be brown because brown is the dominant allele; and if that person has blue eyes, it means they received blue alleles from both parents.

Note: Are you wondering what ‘Types of Eye Color Chart‘ are? They indicate the colors of eyes in three prime categories, including light, dark, and mixed. This classification is done on the regular basic of the Martin-Schultz scale. Eye colors of those who have European origin are light blue – once your kids grow up, some typical changes in the color will begin occurring.

Significantly, there are two main factors that can help you determine the eye color; that are the amount & pattern of dark brown pigment (aka melanin) in the part of your eye and the way in which the iris scatters light passing through the eye. Between these two, which one is more important? The answer is pigment for sure as it’s determined by humans’ genes.
