Data Is Beautiful

Fun fact: the brown-eyed percentage (70-79%) seems to approximately fit the following genetics rule:

+ A  a
A AA Aa
a Aa aa

AA = 25%

aa = 25%

Aa = 50%

50% of Aa + 25% of either aa or AA = 75% probability

I did not know naturally occuring red eyes existed.

Mutant Genes:

Red hair and brown eyes is unusual. Red hair is a recessive trait but brown eyes tend to be dominate. Hair color and eye color are one the same gene, MC1R. So if you have a dominate hair color you tend to have a dominate eye color, brown hair and brown eyes for example. People who have red hair and brown eyes have a mutated gene so the recessive red hair is attached to the dominate brown eyes.

The same concept goes the other way, like people with green eyes and brown hair.

Lots of people in my family have red hair/brown eyes because of this. It doesn’t skip around like it does in some families.

Violet? wtf?

Can eye color change with age? I just checked for the first time in many years and its not what I remembered. Used to be a thin, fuzzy ring of light brown inside a vague cloudy blue. Now it's just cloudy, dull blue. Maybe it changes to accommodate lifestyle and personality
