How Eye Color Genetics Work
Genetic Inheritance
Eye color is determined by multiple genes, but the OCA2 and HERC2 genes play major roles. This calculator uses a simplified model based on dominant and recessive traits:
- Brown: Dominant trait, most common globally
- Blue: Recessive trait, requires specific gene combinations
- Hazel: Mix of brown and green, changes in different light
- Amber: Golden yellow color, quite rare
- Gray: Rare color, often changes with lighting
- Green: Intermediate trait, relatively rare
- Violet: Extremely rare, appears purple/violet in certain light
- Red: Very rare, occurs in albinism or severe lack of pigment
- Black: Very dark brown with high melanin concentration
Important Notes
Disclaimer
This tool provides estimates based on simplified genetic probability models, not medical predictions. Actual eye color inheritance involves multiple genes and can be more complex than shown here.
Did you know? Baby's eye color can change during their first year of life as melanin production increases.
Eye Color Probability Calculator
Our Eye Color Probability Calculator is a simple yet powerful tool that helps parents predict the likelihood of their baby’s eye color. Genetics play a key role in determining traits like brown, blue, or green eyes. With this tool, you can easily estimate probabilities based on the eye colors of both parents. Whether you call it a baby eye color calculator or a baby eye color probability calculator, the purpose remains the same: offering insight into how inherited genes influence appearance.
How Does the Eye Color Probability Calculator Work?
The probability of eye color calculator uses simplified Mendelian genetics to estimate outcomes. Brown eyes are generally dominant, green eyes are intermediate, and blue eyes are recessive. By combining the genetic input from both parents, the eye color inheritance probability calculator assigns percentage chances for each possible outcome.

Eye Color Probability by Parent Combination
| Parent 1 | Parent 2 | Probability Outcome |
|---|---|---|
| Brown | Brown | ~75% Brown, ~18% Green, ~7% Blue |
| Brown | Blue | ~50% Brown, ~0–10% Green, ~40–50% Blue |
| Brown | Green | ~60% Brown, ~30% Green, ~10% Blue |
| Blue | Blue | ~99% Blue, Rare Green, No Brown |
| Green | Blue | ~50% Green, ~50% Blue, Rare Brown |
| Green | Green | ~75% Green, ~25% Blue, Rare Brown |
Eye Color Traits and Genetic Influence
| Eye Color | Genetic Dominance | Notes |
|---|---|---|
| Brown | Dominant | Most common worldwide |
| Green | Intermediate | Rare, influenced by both dominant and recessive genes |
| Blue | Recessive | Less common, requires both parents to carry blue genes |
