The color of your future child's eyes

Many expectant mothers spend a lot of time trying to figure out whose genes are passed on to their children. Will his eyes be the same blue? Or does she have the wonderful green eyes of her aunt Jane?

Almost all children of European descent, regardless of the color of their parents' eyes, are born with blue eyes. This is due to the fact that the pigment "melanin" in the newborn's eyes, which provides dark brown pigmentation, has not yet been produced. The true color of a child's eyes cannot be determined until the age of three.

What determines the color of the eyes

Eye color is a physical characteristic that is determined by a set of genes in both parents.

There are three eye color genes known to scientists, but only two have been studied properly. They explain the transition from brown, green and blue eye colors. However, they do not explain why some children's eyes are gray, light brown, or any other color.

Genes are the basic units of heredity; they identify many of the characteristics of a child. Genes also pass in pairs. "Alleles" are identified in genes and determine whether any traits are present. Each aspect was due to two alleles.

One allele predominates over another allele. It is called dominant, and failure to dominate is called recessive. As for the color of the eyes, the brown allele always prevails over green and blue, the green allele always prevails over blue, and blue, in turn, is always recessive.

Brown eyes are dominant in humans and in many parts of the world. They are present in more than half of the world’s population. The blue color of the eye is the result of recessive genes.
