What will genetics tell?
Genetics scientists have long calculated the probability of what color the eye will have in the child, and recorded their observations in the table, which is presented below:
Everyone knows that the dominant eye color that prevails on the planet is brown. Therefore, if one of the parents is brown-eyed, then the probability of having a baby with brown eyes is very high. Even the owners of green eyes have a probability of a brown-eyed baby, although, of course, a small one.
Very interesting is the theory of dominant and recessive traits. Each person has a certain set of genes. Each of them contains information that, depending on the situation, can be suppressed or, conversely, dominates. According to this theory, you can find out which eyes the child will have in color, shape and even length of the eyelashes. For more details, consider the dominant and recessive signs in the table:
It is also interesting to note that a recessive gene can unexpectedly manifest itself in subsequent generations, which sometimes leads to bewilderment some couples who have a baby with a different eye color.
How does the color of the eyes change?
Determine what eyes the child will have, once he was born, it will not work. All the babies are born with dark blue eyes. It is very rare to see a crumb with darker eyes, almost black. This is typical for children with dark skin, in which there is a large amount of melanin in the body. Beginning with the sixth month of life, the eyes of the crumb begin to change, and the color is set in one child per year, and the others in two or three. Why this happens at different ages, until now scientists have not given an official explanation.
It is very rare to find babies whose nature has been rewarded with unusual eyes: black-yellow or gray-kara-green. Both those and others, are found in the world and are not an anomaly, but people with such eyes are single.
In addition, I want to note that the crumbs can change the color of the eyes in two cases: the transferred trauma and eye diseases, which can affect the color change in the iris.
100% of the answer to the question of what color the eyes should have in the child will not be given to you. With the help of genetics it will be possible only to presume the probability of the birth of a baby with this or that color, and to see what it will be for sure, you can by looking at it in two or three years.
