  • With one parent having Brown eyes and the other having Blue / Gray eyes, the most likely outcome is Brown (50%).
  • There is still a 12% chance of hazel eyes because eye color inheritance involves more than 16 genes, not a simple dominant/recessive pair.
  • Adding grandparent eye colors can shift probabilities by up to 20 percentage points by revealing hidden recessive alleles a brown- or hazel-eyed parent may carry.
  • Eye color can continue to change during the first 1-2 years of life as melanin production matures in the iris.
  • Treat this as entertainment and general interest rather than a genetic test. Parental eye color alone cannot pin down a child's eye color, and even DNA-based tools struggle with the intermediate shades.

Next stepThis is a for-fun prediction, not medical or genetic advice. For any concerns about your baby's vision or eye health, consult a pediatric ophthalmologist.
