Understanding Eye Color Inheritance
Eye color inheritance is a fascinating aspect of genetics. While it's often said that children inherit their eye color from their parents, the reality is more complex due to the polygenic nature of this trait.
Key Points in Eye Color Genetics:
- Multiple genes influence eye color, not just one.
- Each person has two copies of each gene – one from the mother and one from the father.
- Some gene versions (alleles) are dominant, while others are recessive.
- Brown is generally dominant over green and blue, while green is dominant over blue.
- Recessive traits can appear if both parents carry the recessive gene.
It's important to note that a baby's eye color can change in the first few years of life, typically stabilizing by age 3.

Frequently Asked Questions
Can eye color skip a generation?
Yes, eye color can appear to "skip" a generation due to recessive genes. If both parents carry a recessive gene (e.g., blue eyes) but don't display it, their child could inherit two copies of the recessive gene and have blue eyes, even if neither parent does.
When do babies' eyes change color?
Babies' eyes can change color during the first year of life, and sometimes up to age 3. This is because the cells that produce melanin (the pigment that gives eyes their color) are still maturing.
Are brown eyes always dominant?
While brown eyes are generally considered dominant, it's not always the case. The genetics of eye color is complex and involves multiple genes, so there can be exceptions to the general rules of dominance.
