El babies eye color after its newborn may be doubtful. Most Caucasian children are born with the color blue, but it has its explanation, since melamine is part of a main factor to create this color. Until the boy or girl reaches 12 or 18 months of age, the color of the eyes cannot be determined.
To know the precise color you can follow some guidelines based on a calculator that approximates the correctness in a percentage. But it will only be an approximation, since such knowledge can be achieved by letting time pass. You don't have to trust him eye color when born but as the months go by, he will be pointing out what color he will stay with.
How long should you wait to find out the baby's eye color?
Everything will depend on the melamine, a substance that is present at birth and that it will resolve the tonality of the skin, the eyes and even the hair. So you have to wait a year and even a little more time pto determine exact data. There are cases in which melamine can act up to 3 years. In many cases, the eye color already darkens by six to eight months of age and therefore will be the color he sticks with.
Can eye color be calculated?
It can be calculated, but only it will be an accurate data that could fail. There is no exact calculation, since there have been rare cases where the parents had brown eyes and have a baby with blue eyes. Or even brown-eyed parents with a brown-eyed baby. But this can only happen when some of parents have a recessive gene, since there is a relative who has this gene and causes it to be inherited from the grandchildren.
From here you can create a precision calculator, but as we have reviewed, it will only be to give an approximation. When parents have brown eyes it may be logical to have children with brown eyes. The same goes for parents with blue eyes as they can have children with blue eyes. But what happens when there is a color difference between the parents?
- When one of the parents has brown eyes and the other blue eyes, the probability is one 50% chance to have blue or brown eyes. One of the possibilities may be to have green eyes.
- When one of the parents has the green eyes and the other brown, the probability will be 30% green eyes, the other possibility points to a 50% brown and 12% blue.
- If one parent has the blue eyes and the other green, we have a probability of 50% blue and the other 50% green.
- For brown eyes in both parents there is also a percentage. The probability points to a 75% that the baby has brown eyes, 18% green and 6% blue.
Several aspects must be nuanced. This type of calculator is only data to give an indicative color, since his is study the family environment to match various aspects. Many times the color can give us more than one surprise, especially when children have blue eyes.
The blue color is a pretty color, but that will depend on tastes. We must point out the second nuance, which brown will always be more dominant than blue. In order to give an exact and pure color, two dominant colors must match and that can interfere with concluding a true blue. This color needs the strength of chromosomes 15 and 19, since being a less dominant color, the probabilities will be reduced.
