Baby Eye Color Calculator
Curious about your baby’s eye color? Compare parental traits and see estimated probabilities for brown, green, and blue eyes.
Baby Eye Color Predictor
Select each parent’s eye color. Add grandparents if known to refine hidden-allele assumptions.
How This Baby Eye Color Calculator Works
This calculator uses a simplified educational model where brown generally dominates over green and blue, and green dominates over blue. It estimates hidden parental alleles from phenotype and then combines those probabilities to produce likely baby eye-color outcomes.
Simplified inheritance assumptions
Brown > Green > Blue (educational dominance hierarchy)
Optional grandparent colors can refine hidden-allele assumptions, which can slightly shift probabilities—especially for recessive blue outcomes.
Important limitation
Real eye color is influenced by multiple genes, not just one dominance chain. Treat the output as a fun educational estimate rather than a definitive genetic prediction.
