The most interesting thing for future parents is to thinkA girl or boy will be born, whose baby has a nose and what eyes will it have - blue, like mom's, brown, like grandfather, or maybe green, like great-grandmother? With the floor somehow simpler, on the ultrasound, if the mother wants, with a high degree of probability they will say who will be born, but what about the eye color? After all, so can not wait to quickly imagine how the crumb will be born! With appearance everything is not so simple, but the "mirror of the soul" ... You can assume the color of the eyes of the child. The table for determining the shade of the iris exists and will help in this.
Eyes of a newborn
What will be the color of the eyes of the crumbs, laid inthe first trimeter of pregnancy, more precisely by its end, on the eleventh week. But almost without exception, babies are born with blue-gray-violet eyes, only occasionally there are dark newborns. This does not mean that the color will not change. By about a year, sometimes even by three to five, eyes become as their nature conceived, or, if you like, which genes prevail in a baby. The child's eye color changes in time for this period of life, starting from 6-9 months. Only in the brown-eyed he will become permanent in the first months. It happens that a baby is born with eyes of different color. This phenomenon occurs in about one percent of 100 cases and is called heterochromia.
Melanin, responsible for eye color and eye-catchingwhen light hits, in the mother’s tummy is simply not produced. This explains why all newborns have the same irises. So, do not torture yourself, trying to see the color of the eyes of your beloved crumbs. Be patient, you will soon see what he is in the baby.
Child's eye color and genetics
Многие помнят, как на уроках по биологии it was said that brown eye color dominates the rest. This, of course, is true, but even if the eyes of both mom and dad are like that, there is still a small chance to have a green-eyed child or with a blue iris. So in the direction of jealousy, turn on the brain and begin to understand why, what and why. It is no secret that some couples break up just because the brown-eyed parents have a light-colored baby.
Of course, based on science, you can understandgenetics. After all, she gives the answer to the question of what color the child will have eyes. There is a law of Mendel, according to which the eyes, like hair, are inherited according to the principle of the predominance of genes responsible for dark color. Gregor Mendel - a monk scientist more than a hundred years ago discovered this law of inheritance. For example, in dark parents and children, with a high degree of probability, they will be the same, and in light parents - on the contrary. A child born of people of different phenotypes may be average in color of hair and eyes, between the two. Naturally, there are exceptions, but this is rare.
Eye color detection
All of the above can be presented as a table. According to it, each person will presumably determine the color of the baby’s eyes.
| eye color of parents | baby's eye color | ||||
| brown | green | blue (gray) | brown | green | blue (gray) |
| ++ | 75% | 18.75% | 6.25% | ||
| + | + | 50% | 37.5% | 12.5% | |
| + | + | 50% | 0% | 50% | |
| ++ | about 0% | 75% | 25% | ||
| + | + | 0% | 50% | 50% | |
| ++ | 0% | one% | 99% | ||
Understand easy, what will be the color of the child's eyes. Table, according to which it is possible to do this, confirms the law of Mendel, but all the same exceptions to the rules remain as a small percentage. How nature will dispose, no one knows.
By the way, the fact that dark color isdominant at the gene level, led to the prevalence of brown-eyed people around the world. According to some reports, the bright color of the eyes of a child will not occur at all in the future.
The most interesting about the color of the iris
According to scientists, there were no blue-eyed people ten thousand years ago. All with such a shade of the iris, one ancestor, according to researchers.
Зеленый цвет глаз имеет меньшее количество людей, than anything else. Due to the fact that only every fiftieth inhabitant of the globe has this shade, at different times and among different nations, according to tradition, they were burned at the stake, then praised and treated with respect, endowing with magical powers in both cases. And brown-eyed and today we hear that they have a bad eye and they can jinx someone.
Among the various variations of the three main shadesthe iris is very rare to meet people with red eyes from the blood vessels. Although they look unpleasant and even scary, but it is not to blame for the fact that they were born albinos. Melanin, due to which the irises of the eyes differ in color, is practically absent in such people.
The eyes are the mirror of the soul
И еще один интересный факт, кто-то обращал на his attention, someone does not, but the color of the eyes of most, if not all, light-colored people changes depending on the mood, well-being, color of clothes, in stressful situations.
Not an exception and the color of the child's eyes.The table above does not tell about it, and there are no specific rules here. All individually. Basically, when the baby is hungry, his eyes darken. He wants to sleep and is capricious - becomes muddy. If crying, the color is closer to green, and when everyone is happy - to blue. Maybe that's why they say that the eyes are the mirror of the soul.
Many parents of the future baby and their relativestrying to determine the color of the eyes of a child. The table created for this helps them, of course. But it’s more important that the baby is born healthy. And it is much more interesting to observe how the baby will change and what its eyes, nose, hairs will become, and not know in advance. The baby will grow up, and you will see that it is light or vice versa.
