Can Two Brown Eyed Parents Have a Blue Eyed Baby?

As mysterious as it may seem, it is indeed possible for two brown eyed parents to have a blue eyed baby! According to genetics and science, eye color is actually determined by more than just the color of the eyes of one’s parents.

What Factors Determine Eye Color?

Eye color is affected by a combination of both genetics and that individual’s environment. The primary two factors that determine eye color are:

  • The genes a person carries– While parents typically pass down genes that typically show the most dominant trait for characteristics like eye color, some eye colors are recessive and can still prevail, even though they are not dominant.
  • Mutations– Mutations can cause colored eyes in the absence of any labeled “colored eyes” gene trait.

How Rare is It?

This variation occurs in less than two percent of the population. Blue eyes are the result of an uncommon recessive gene trait, which means two blue eyed parents are more likely to have a blue eyed baby, but brown eyed parents can still have a blue eyed baby if they both carry the recessive gene.

Conclusion

In conclusion, while eye color is predominantly determined by the genes of one’s parents, there is still a possibility for two brown eyed parents to have a blue eyed child. It is not a common gene trait, but with the help of mutations, blue eyes can appear in the absence of any labeled “colored eyes” gene traits.
