Which Eye Colour Will Your Baby Have?
Researching eye colour is a very captivating topic. For many centuries scientists tried to gather all the necessary information and find out the nature of colouring. Nowadays we know that eye colour is a hereditary thing. When you are eager to make a forecast concerning the eye colour of a baby born, you can know for sure, the colour will be blue. Almost in 100% cases each human being is born with this eye colour that gets darker with time because of the influence of the sunlight. At the age of 3 or 4 a child’s eye colour becomes permanent. And today we distinguish different shades all of which are unique.
There is a simple scheme that shows the chances of a certain colour to dominate:
Brown + Brown = Brown 75%, Green 18, 75%, Blue 6, 25%
Green + Brown = Brown 50%, Green 37, 5%, Blue 12, 5%
Blue + Brown = Brown 50%, Green 0%, Blue 50%
Green + Green = Brown <1%, Green 75%, Blue 25%
Green + Blue = Brown 0%, Green 50%, Blue 50%
Blue + Blue = Brown 0%, Green 1%, Blue 99%
In order to understand this formula you should understand the mechanism of inheritance. It’s a common opinion that eye colour is inherited according to the Mendel’s law: dark coloured genes are dominant. The same is applied towards hair colour. Dark haired parents are likely to have a child with hair of the same colour; and in families where hair colour of parents differs from each other, the baby will have medium coloured hair. But of course, there are exceptions.
It doesn’t really matter which eye colour your baby will have. All the eyes in the world are beautiful. And with the existence of so many tone variations, you are unlikely to find someone with exactly the same colour. Eyes reflect our personality, inner warmth and kindness. And to show that all colours are precious, we have for you several interesting facts:
The most widespread eye colour in the world is brown. The rarest one is green. Less than 2% of world’s population has eyes of this colour. The biggest number of green eyed people live in Turkey (20% of all the population). There are some countries in Asia, South America and the Middle East where there are no people with these eyes at all. For those who live in the Caucasus, blue eye colour is considered to be the norm, and more than 80% of Icelanders have either blue or green eye colour. The less pigment in the eye generally means the higher latitude that you live in, and the more susceptible the eye is to damage. People with brown eyes tend to live in sunnier climates, while blue eyed people don’t, therefore they are much more in need of both standard and prescription sunglasses.
And a few words about a rare phenomenon called heterochromia that results in that a person has different colours of eyes. Mila Kunis and David Bowie are representatives of such people, however Bowie’s eye colour is the result of football trauma he got at his childhood. One thing you can be sure is that your child’s eyes will be the most beautiful in the world!
