Baby Eye Color Calculator 2026
Predict your baby’s likely eye color based on parental genetics. Understand dominant and recessive traits with our easy-to-use probability tool.
Parental Genetics
Select the eye colors of both biological parents
Recessive genes can hide for generations. Selecting this slightly increases the chance of lighter eyes.

Baby Eye Color FAQ
Everything you need to know about genetics, dominant traits, and how your baby’s eye color is determined.
Eye color is determined by the genetics inherited from both parents. It involves multiple genes, but primarily the OCA2 and HERC2 genes on chromosome 15. Brown is generally dominant over green, and green is dominant over blue.
While extremely rare, it is biologically possible due to complex genetic mutations or if the parents carry hidden dominant genes from previous generations. However, in standard Mendelian genetics, two blue-eyed parents will almost always have a blue-eyed baby.
Most babies are born with blue or grey eyes due to a lack of melanin. The final eye color typically stabilizes between 6 to 9 months of age, though subtle changes can continue up to 3 years old as melanin production increases.
Yes, the allele for brown eyes is dominant over the allele for blue eyes. This means a person only needs one copy of the brown gene (from either parent) to have brown eyes, whereas blue eyes require two copies of the recessive blue gene.
Yes, eye color can appear to skip a generation. If a grandparent has blue eyes (recessive) and passes the gene to a parent who has brown eyes (dominant), that parent can then pass the blue gene to their child, resulting in a blue-eyed grandchild.
