Each future mother with tenderness and awe expects the kid. Who there - the boy or the girl? On whom will it resemble - me or the father? What will be character, what mind, what hair color, color of eyes?
Practically all people at least once heard the widespread myth that color of eyes at all newborns - celestial-blue. Actually, it not absolutely so. At such age all kids color of eyes really almost identical, but can have it grayish, mutno blue or bright blue. The quantity of a pigment of melanin at babies is small, it increases within the first year of life and the intensity of development affects final color of eyes of the child. This process at all kids comes to the end at the time, but in most cases by a year it is possible to define constant color. However change of subtle shades in certain cases lasts up to 3-4 years.
What does the intensity of production of melanin depend on? Generally from heredity. But you should not understand it too simply - color of eyes of the child it will not be obligatory same, as at one of parents or mix of their flowers. On this subject it will be useful to educate jealous and full prejudices of the spouse, in order to avoid misunderstanding.
So, color of eyes of the child can differ also from color of eyes of mother, and the father. But some guesses on the basis of parental lines can be offered. If both parents brown-eyed - the child are the same in 75% of cases. Are also possible green (20%) and blue (5%) color of eyes. If one parent brown-eyed, and another green-eyed, then in half of cases the child inherits brown eyes, in 40% green and in 10% blue. Brown-eyed and blue-eyed parents also in 50% will receive the brown-eyed child, other 50% will be blue-eyed, and here green eyes in this situation most likely will not turn out. Green-eyed parents will give birth to the same child in 75% of cases, in a quarter of cases of an eye of the offspring will be blue, and in the most improbable case (<1%) the brown-eyed child will be born. The union of blue and green eyes will hardly give brown-eyed posterity, and the colors will be distributed with the equal probability (50%). And, at last, two blue-eyed parents from 99% chance will receive the same child. In 1% of cases they will give birth to the kid with green eyes, and the brown-eyed child at such couple will hardly appear. There are some cases when this regularity can be inapplicable. Sometimes people meet unusual appearance - they have eyes of different color. Though there passed those times when they were considered witches, supporters of a devil and in every possible way avoided, such line of appearance all the same surprises and draws attention. However, it does not cause any loss of appeal. The kid can be born your exact copy or on the contrary, at all will not resemble you, he can have eyes of your husband, a curly of your mother or a freckle of your father. Whether it is important? Probably, it is more important to do everything possible that your child grew at the happy and worthy person - it is inheritance and will be your main gift to it.
