Research question

[eleneariel]

It's vital to know for my nanowrimo novel whether all babies are born with blue eyes or not. A child who will grow up to have very dark brown eyes, would they still be blue at birth? And if so how soon would they change?

I love having knowledgable friends.

I'm almost positive that children with dark eyes later in life are not born with blue eyes. I don't think any of us kids were born with blue eyes. ::trots off to ask Mother::

Nope, none of us were born with blue eyes. We all have medium to dark brown eyes now (and then).

Many caucasian babies are born with blue eyes, but not all. In my family, only Matthew was born with blue eyes-- the rest of us had dark eyes. Chances are, if a baby has any ethnic blood (we have American Indian ancestors, for instance), she will have dark eyes when she is born.

It's entirely based on genes and won't change. Once the baby is formed, the eye color is what it will always be (unless some strange mutation or something occurs). So, babies can be born with any eye color.

Now, two dark-eyed parents can produce a blue-eyed child, if they both have a recessive gene for it that will appear. So it's not based on the parents' eye color as much as what traits they are carrying and which pass on. Does that make sense?

My brother and sister and I all had brown eyes at birth, and still do.
