Are Blue Eyes Are Recessive?
You may be hearing from your mom, your mother-in-law, and the cute old lady who lives next door that every baby is born with blue eyes, but is that really true? Well, no, not EVERY baby is born with blue eyes, but it is true that many babies are born with blue eyes that do change over time. And although traditionally we may view brown eyes as being the dominant gene and blue eyes being the recessive gene, it isn’t that simple when it comes to eye color.
In order to fully understand why so many babies are born with blue eyes, you need to understand the science behind it.
What is Melanin?
Melanin is a pigment in the eyes that causes them to become darker— either more green or more brown over time. However, the majority of babies are born without melanin in their eyes which causes them to be blue or even a gray color. As your baby grows and develops, they may also start to produce more melanin— which is genetic— that will cause their eyes to change color by around age 2-3.
What Do Genetics Say?
When it comes to genetics, there really isn’t a distinct formula that will help you to predict what color eyes, hair, or even skin color your child is going to have. And although if you and your spouse both have brown eyes, your child is more likely to have brown eyes as well, there really isn’t any sort of guarantee.
When it comes to understanding eye color, it really can be hard to predict whether or not your blue-eyed baby is going to stay blue-eyed or if they are going to change. However, by understanding a little bit of the basic science behind changing eye color, you can help to be a bit more informed the next time your mom or mother-in-law claims to know your the outcome of your child’s eye color.
