What will your kid’s eye color be?
The Department of Genetics at the Stanford School of Medicine in partnership with the Museum of Innovation has launched an online genetics eye color calculator which takes into account your eye color and that of your partner to figure the probability of your potential kids inheriting a certain eye color.
Of course the results are speculative and do not take into account all the vast influences of other hereditary factors but it's still fun to use! The calculator works by taking into account your eye color, that of your parents and siblings, and the eye colors of your partner and their immediate family. By doing this, the program can then get a combination of possible genotypes that you can pass on to your child. The genotype for eye color, in this case, is a kind of biological map that determines what eye color will be expressed in the eye. Because many possible combinations of genotypes exist for a potential child, the calculator only returns the chance of inheriting a certain eye color.
But keep in mind, some eye color of babies can change in the first few years of life where, for example, many babies are born with blue eyes but then develop green or brown eyes. According to the U.S. National Library of Medicine, this might be attributed to the increase in melanin, the gene associated with eye color, in the iris which changes the color of the eye we see.
That being said, use the Museum of Innovation's eye color calculator and satisfy your curiosity!
