Predicting Babies’ Eye Color

I am completely obsessed with genetics. I find the manner in which dominant and recessive genes combine to form a phenotype (i.e. the trait that displays) positively fascinating. I write about predicting babies’ features a lot on this blog because: 1) I think it’s so damn interesting and 2) You can actually predict what your future child may look like with just a few inputs.

I created the chart below to help you predict what eye color your baby may have. It’s a very simple eye color predictor, as it only takes into account the eye color of the parents:

If you know the eye color of the grandparents (as I’m guessing most of you do), you should check out TheTech’s baby eye color predictor. The more info you can provide it, the more accurate your eye color predictions will be.

Did You Know…?

  • Brown is the most common eye color across the world. It is also the most common eye color in the U.S. today.
  • In 1900, blue was the most common eye color in the U.S., with approx. 58% percent of people having blue eyes.
  • Most babies are born with blue eyes, regardless of the color they will ultimately be.  Children’s eye color may change during their first few years. Usually, by the third birthday, a child’s eyes will take on their permanent color.
  • Your eyes don’t grow. Their size at birth is the size they will always be.
  • Having two different colored eyes (e.g. one brown, one green) is extremely rare but does occur. This condition is called heterochromia.

  1. So cool! I’ve got green eyes, Mike has blue. 4 of the kids have green, 4 have blue–so we fall right in line with the chart! Now this is interesting–we have friends, the wife with gorgeous green eyes and the husband with piercing blue–but both of their biological kids have brown eyes—hmmmm. Maybe they didn’t read the chart…;o)

    Blessings!

  2. 1% chance of blue eyes if both your parents have blue? I guess judging by this, large parts of Europe was a fluke. Btw- I have green eyes, so does my brother. My parents have blue brown respectively. Judging by this chart, that is not even a fluke, but a miracle. And yes, dad is my dad.

    I can not belive no one has commented on this stuff sooner.

  3. seems like if noth parents have blue, both recessive, there would be a greater chance of blue than 1%. all of my family has blue eyes, and with a 1% chance for each kid, you’d think one would get green eventually, considering my generation has 27, and my parents’ has 8, including spouses. just on my dad’s side. its also not very acurate to give a 0% chance. because only one exmple can negate the whole rows accuracy, if not the chart.
