How This Calculator Works

Uses multi-gene Mendelian matrix models (HERC2/OCA2) to estimate final eye color probabilities.

Baby Eye Color Genetics Calculator

Discover the genetic possibilities of your baby's eye color based on parent phenotypes.

The Polygenic Nature of Eye Pigments

The iris contains melanin pigments. High concentrations create brown eyes, medium yields green, and absence creates blue eyes.

Grandparent Genetic Influence

Carrying recessive alleles from grandparents can lead to unexpected and beautiful eye color outcomes.

Clinical Standard Reference Guideline:

Duffy DL, et al. Multiple genetic loci determine human eye color.

Frequently Asked Questions (FAQ)

Q:Can blue-eyed parents have a brown-eyed baby?

While rare, yes. Eye color genetics is a polygenic trait involving multiple genes, not just a simple dominant-recessive Mendelian locus.
