What Color Baby Eyes Calculator

Determine the probability of your baby's eye color using our genetics-based calculator. Eye color inheritance follows specific patterns based on parental eye colors and genetic factors.

How the Calculator Works

The eye color calculator uses genetic probability models to estimate your baby's eye color based on your and your partner's eye colors. The calculation considers:

Parental eye color combinations
Genetic inheritance patterns
Probability percentages

This calculator provides estimates based on general genetics principles. Actual eye color may vary due to environmental factors and other genetic influences.

Genetics Basics

Eye color is determined by multiple genes, with the most significant being the OCA2 gene. The basic inheritance patterns are:

Blue eyes: recessive trait (bb)
Brown eyes: dominant trait (B-)

Other eye colors like green, hazel, and gray are influenced by additional genes and environmental factors.

Probability Factors

The calculator considers these probability factors:

Parental eye color combinations
Genetic inheritance patterns
Possible mutations
Environmental influences

Probability = (Number of favorable outcomes) / (Total possible outcomes)

Example Calculations

For parents with brown eyes (B-):

Brown eye probability: 75%
Blue eye probability: 25%

For parents with one brown eye (B-) and one blue eye (bb):

Brown eye probability: 50%
Blue eye probability: 50%

Frequently Asked Questions

Is the calculator accurate?: The calculator provides estimates based on general genetics principles. Actual eye color may vary due to environmental factors and other genetic influences.
Can the calculator predict exact eye color?: No, the calculator provides probability estimates. Other factors like environmental influences can affect the final eye color.
Does the calculator work for all eye colors?: The calculator focuses on blue and brown eye probabilities. Other eye colors like green, hazel, and gray are influenced by additional genetic factors.
