By the color of the eyes of a newborn, it is impossible to immediately determine whether he looks like his mother or his father, since the eyes acquire their native color only over time. This is due to the fact that the body produces and accumulates melanin gradually.
Instructions
Step 1
The color of babies' eyes can change during the first year of life, sometimes this process is delayed for a longer period. It should be noted that newborns have very poor eyesight, initially they can only react to light. As they grow older, visual acuity increases and by the year it is about half the norm of an adult.
Step 2
In the first days after birth, the baby's vision must be checked by the reaction of the pupils to light. By the second week of life, the baby can already fix his gaze on a specific object. By the age of six months, the child is able to distinguish between relatives, simple figures and toys, and in a year - rather complex images.
Step 3
Skin tone, hair color, and eye color depend on the presence of a pigment called melanin. The eyes of most newborns in the first few months of life are light gray or light blue, since there is simply no melanin in their irises. As a child develops and matures, his body begins to produce and accumulate melanin, which leads to a change in eye color, skin tone, and sometimes hair. If the eyes darken, it means that a lot of melanin has accumulated, if the eyes remain light, acquiring a more pronounced shade (gray, blue or green), this means that little pigment has been developed.
Step 4
In some children, eye color changes several times. This suggests that pigment production may have changed with growth and development. The final color of the eye is acquired when the child reaches three to four years of age.
Step 5
The amount of melanin is influenced by heredity. The reason is the dominance of genetic traits. A child receives a set of genes not only from his father and mother, but also from distant ancestors, respectively, he has a unique hereditary fund that belongs only to him. It is thanks to this genetic fund that individual traits appear and develop, and the unique characteristics of the child's body are formed.
Step 6
It should be borne in mind that dark eye color is a dominant genetic trait, so if one of the parents has light eyes, and the other has brown eyes, it is highly likely that the child will have dark, brown eyes.
Step 7
In some cases, in light-eyed people, stress and illness can cause eye color changes. Blue, gray, or green eyes can turn yellow and dull. With brown eyes, as a rule, nothing like this happens.
