Eye Color Punnett Square Calculator
Predict eye color inheritance patterns with our specialized eye punnett square calculator. Analyze brown, green, and blue eye genetics to understand genetic eye color probabilities in offspring.
Eye Color Inheritance Calculator
Parent 1 Eye Color Genotype
B = Brown (dominant), G = Green (intermediate), b = Blue (recessive)
Parent 2 Eye Color Genotype
Eye color genetics involves multiple genes, but this calculator focuses on primary inheritance patterns.
Understanding Eye Color Genetics
Eye color inheritance is more complex than simple dominant-recessive patterns. Our eye color punnett square calculator focuses on the primary genes that determine brown, green, and blue eyes, making genetic eye color prediction accessible for educational purposes.
Dominance Hierarchy
- Brown Eyes (B): Dominant over green and blue
- Green Eyes (G): Intermediate dominance over blue
- Blue Eyes (b): Recessive to both brown and green
Genetic Factors
- Melanin production and distribution in the iris
- Multiple gene interactions beyond simple inheritance
- Environmental factors during eye development
- Age-related changes in eye pigmentation
Eye Color Statistics & Facts
Brown Eyes
Most common globally (~79% of population). Caused by high melanin content in the iris.
Blue Eyes
Found in ~8-10% of population. Results from low melanin and light scattering (Rayleigh scattering).
Green Eyes
Rarest at ~2% globally. Combination of moderate melanin and lipochrome pigments.
Clinical Applications
Eye color genetics helps in forensic science, medical genetics, and understanding population ancestry patterns.

Frequently Asked Questions
How accurate is the eye color punnett square calculator?
Our calculator provides educational estimates based on simplified genetic models. Real eye color inheritance involves 15+ genes, making actual prediction more complex than basic Punnett squares can represent.
Can eye color change over time?
Yes, eye color can change, especially in babies during their first year. Some adults may experience slight changes due to aging, medical conditions, or medications affecting melanin production.
What about hazel or amber eyes?
Hazel and amber eyes represent intermediate phenotypes involving multiple genes. Our simplified calculator groups these with brown or green categories for basic inheritance pattern analysis.
How does this help with baby eye color prediction?
While useful for understanding genetic principles, actual baby eye color prediction requires considering multiple genes and environmental factors. This tool provides educational insight into inheritance patterns.
