How does the baby eye color predictor work?

We estimate probabilities using a simplified genetics model where brown typically dominates green, and green dominates blue. Real eye color is polygenic (genes like HERC2/OCA2 and others), so we return likely percentages rather than certainties.

Can two blue-eyed parents have a brown-eyed baby?

It’s uncommon but possible — MedlinePlus Genetics notes that parents with blue eyes can have children with brown eyes because several genes are involved. Our simplified model gives 99% blue for two blue-eyed parents and shows brown and green as “about 1%: unlikely, but possible”.

When do a baby’s eyes change color?

Newborn eye color can shift during the first year as melanin builds in the iris, with the biggest changes often between 3 and 6 months. Blue may deepen to green, hazel, or brown. Most babies have their lasting color by 12 months, but subtle shifts can continue up to about 3 years.

How accurate is an eye color calculator?

It provides probability estimates, not guarantees. Eye color is influenced by multiple genes and modifiers. Use the results as a fun, educational guide—only genetic testing can give definitive insight.

Do grandparents’ eye colors affect my baby’s eye color?

Yes, extended family can influence outcomes because parents carry combinations of dominant and recessive variants. That’s why two brown-eyed parents can still have a green- or blue-eyed child, and vice versa.

Does ethnicity change the probabilities?

Population genetics vary by ancestry, so baseline frequencies of brown, green, and blue eyes differ among groups. Our simplified model doesn’t adjust for ethnicity, but real-world odds can shift with background.

Brown vs. green vs. blue: which is most dominant?

In simplified terms: brown > green > blue. However, multiple genes and regulatory regions (e.g., HERC2/OCA2) interact, so dominance isn’t absolute. That’s why we present **probabilities** rather than yes/no outcomes.
