Baby Eye Color Predictor
Wondering what color eyes your baby might have? This baby eye color calculator uses the genetics of the parents’ eye colors to estimate the most likely outcomes, based on both heterozygous and homogenous inheritance models. It’s a fun and educational tool for expecting parents.
Predict Your Baby’s Eye Color
Eye Color Probability Formula
This formula is based on Mendelian genetics. Probabilities vary depending on whether the model assumes **heterozygous** (more diverse gene variants) or **homogenous** (less diverse) inheritance. For example:
- Two blue-eyed parents (heterozygous) have a 99% chance of a blue-eyed baby.
- A brown-eyed and blue-eyed pair (heterozygous) have a 50% chance for either color.
- In homogenous inheritance, brown eye genes dominate—almost always resulting in brown-eyed offspring if one parent has brown eyes.
Eye color is determined by multiple genes, but simplified inheritance models can predict likely outcomes using basic genetic rules. This calculator assumes two types of models:
- Heterozygous: Each parent carries different gene variations, leading to more diverse outcomes.
- Homogenous: Each parent carries two identical gene copies, often resulting in dominant traits (like brown eyes) prevailing.
This tool is useful for expecting parents curious about their baby’s appearance and interested in learning more about inherited traits.
