Have you wondered about different coloured eyes, and how people inherit them?
As you might have noticed, there are different people with different eye colour. These eye colours can vary from grey, hazel, blue, green, and brown.
Eye colour is a physical trait determined by the pairing of genes from both the parents.
But do you know that the eye colour is actually the iris colour? There is a pigment known as melanin present in your iris which produces your eye colour.
For example, blue eyes are produced due to lack of melanin while brown eyes are produced by higher concentrations of melanin. The resultant eye colour can be of any shade which is further determined by genetics.
The colour of the iris, like the colour of hair and skin, depends on this melanin.
We have specialized cells in our bodies called melanocytes whose job it is to go around the melanin that is secreted where it is needed, including in the iris.
Over time, if the melanocytes only secrete a little melanin, your baby will have blue eyes. If you secrete a little more, your eyes will look green or hazel.
When the melanocytes are really busy, the eyes appear brown (the most common eye color) and in some cases, they can appear very dark.
Because it takes about a year for the melanocytes to finish their work, it can be hard to tell the color of the eyes before the baby is 1 year old though the color change generally begins to stop after the first 6 months of life,
What Colour Will My Babies Eyes Be?
Eye colour is a genetic property, but it is not as pre-established a matter as you might have learned in biology class.
Two blue-eyed parents are more likely to have a blue-eyed child, but this does not always happen.
Two brown-eyed parents are more likely (but not guaranteed) to have a brown-eyed child.
If you notice that one of the grandparents has blue eyes, the chances of having a blue-eyed baby increase a bit.
If one parent has brown eyes and the other parent has blue eyes, the odds are about the same for eye colour.
What colour are your eyes what colour do you think your babies eyes will be?
