Many parents are curious as to what the eye color of their children, are you one of them? In some cases the answer may be more or less clear, but genetics is very capricious, even in those cases that we believe to be simpler, it can surprise us. But we can calculate the probabilities that they are brown, blue, or green. As? Using an eye color calculator, based on the color of the eyes of parents and grandparents.
Today there are online tools for all. Yes, also to calculate the color of our son's eyes! This will be determined by the genes, mainly those involved in the production, transport or storage of a pigment called melanin. Are you curious about what determines eye color and how to use these online calculators? We find out for you!
genetic trait
The color of the eyes, as we have already mentioned, is a genetic anatomical trait. It will depend, fundamentally, on the genetics of the eye color that you inherit from your parents and grandparents through chromosomes 15 and 19 and on the combination of these. Several genes are associated with eye color, the most important being...
- EYCL1: Responsible for determining the green and blue colors It is located on chromosome 19.
- EYCL2: Main person in charge of Brown color, is located on chromosome 15
- EYCL3: It is one of the genes that regulates the amount of melanin of our organism.
The color of eyes is determined by the amount and the melanin distribution in the iris and there are three elements of the iris that contribute to this: the melanin of the iris epithelium, the melanin of the anterior part of the iris and the density of the iris stroma. Being the pigment of the anterior part of the iris and the amount of light absorbed by the stroma according to its density, those responsible for the variation in eye color. But let's not get technical! having at our disposal not one eye color calculator but several.
eye color calculator
Eye color genetic calculators are based on a very simple model. Some use only information about the mother and father to calculate the probability of a child's eye color. However, most nowadays also play with the grandparents' eye color to obtain a slightly more precise result.
Do you want to play the odds? You must bear in mind that although the result will be the most probable, it does not have to coincide with reality and it is as we have already anticipated, genetic inheritance is very capricious! These are the two calculators that we liked the most for their simplicity:
Predict Eyes
Es very simple and intuitive. You will find six characters (maternal grandparents, paternal grandparents, mother and father) whose eye color (brown, blue, green or indefinite) you will have to select by clicking on each figure. Once selected all the results and their probability will appear below. Try it!
Baby Eye Color Predictor
Do you prefer to do it from a application on your mobile? Baby eye color predictor is a tool very similar to the previous one. Select the eye color of grandparents, father and mother to find out how likely your child is to have brown, green or blue eyes.
This tool in addition to the eyes will allow you calculate other features such as hair color, chin shape, or whether you might be lactose intolerant. Are you curious? You can download it in the Play Store.
Keep in mind that many newborns have blue eyes and that these over time derive in a different tone. It happens because when they are born they are not capable of producing melanin, which, as we have already explained, is the substance that provides the color to the iris. So if the color doesn't match what the eye color calculator predicted, wait until he's a year old to yell that it doesn't work!
