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.
My wife has brown hair, brown eyes and an olive skin complexion. I’m your typical scandi with reddish-blonde hair, blue eyes, skin that burns like paper.
Our child has brown eyes, red hair and olive skin that actually tans. It’s bizarre.
Can I ask what color your kid’s freckles are? I ask, because the redheads in my family have orange freckles, and the non-redheads have brown freckles. It looks like that correlates with the type of melanin, which would also affect whether they tan.
I have brown hair and brown eyes. My wife has blond hair and green gray eyes. We have a son with red hair and blue eyes. And yes he is my son. Genetics are weird.
Weird. Never thought it to be real. In Warhammer 40k, only a populace of a specific planet has those purple eyes. Kinda neat to know that this might have been a super-specific random event (first human settlers of that planet having purple eyes).
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
My partner tells me that my eyes fluctuate between blue and green. I can’t really tell for sure. I always go look in the mirror when she comments about them. Maybe I should start taking selfies to compare.
Wow, that's crazy. I'm Australian (Australian Dad & Kiwi Mum) but I actually have Irish in my heritage. I am also the only one in the family to have red hair which was apparently a massive coincidence only possible because of DNA that by chance was on both my Mum's side and my Dad's side (I don't know the fine details). Until I was 13-14, my eyes used to change colour between Green and Blue depending on the time of year. Now I'm approaching 23 and my eyes have consistently been green since around 14.
Can you post a pic of someone with black eyes? That sounds wild, and I'm curious what its like in your world where half of people just have pupils and no iris.
