Predict Your Baby's Eye Color
One of the most exciting questions for expecting parents is, "What will our baby look like?" Our Baby Eye Color Calculator uses standard genetic models to estimate the probability of your child having Brown, Blue, or Green eyes based on the parents' phenotypes.
How Eye Genetics Work
Eye color is determined by polygenic inheritance, meaning multiple genes play a role. The two main genes are OCA2 and HERC2.
- Brown: The dominant trait. If you have the brown gene, you will likely have brown eyes.
- Blue: A recessive trait. You generally need two blue genes (one from each parent) to display blue eyes.
- Green: A mix. It is dominant over blue but recessive to brown.
Frequently Asked Questions
Can two brown-eyed parents have a blue-eyed baby?
Yes, it is possible if both parents carry the recessive blue-eye gene. However, the probability is relatively low (around 6.25% to 25% depending on carrier status).
Is this calculator 100% accurate?
No predictor is 100% accurate because eye color genetics are complex and can be influenced by at least 16 different genes. This calculator provides the most likely statistical outcomes.
When do babies' eyes change color?
Most Caucasian babies are born with blue or gray eyes that darken over time. Permanent eye color is usually established by age 3.
