2 green eyed parents, brown eyed child

[SplitFountainPen]

Can someone explain this genetically?
Dh and I both have very similar green eyes with a tiny circle of brown around the center, primarily green though.
Our DC1 has solid brown eyes, all one colour.
DC2 has solid green eyes, all one colour.

My DPs have brown and blue eyes, PILs have green and blue eyes.

Why do I not present with brown eyes if I have carried that trait to pass it on? Though how can I have when I should be carrying green dominantly and blue recessively to have green eyes?

No question of us not being their parents, just purely curious!

I always understood the brown eyed colour gene is the "dominant gene" and other colours - blue , green, hazel were recessive so if there are two parents with green, hazel or blue eyes but either of those parents have a brown eyed gene - through one of their own parents- then a brown eyed baby will be the outcome.

In fact contrary to what Anyway is trying to claim, it's far more likely for two parents of any eye colour to have a brown eyed baby than a baby of any other eye colour.

The inheritance of eye colour is massively complicated. The genetics we all learned at school comes nowhere near explaining it, it isn’t just oversimplified it’s actually wrong. You can’t work it out with a diagram using lower and upper case letters and lines.

This!

So you have seen it too, many sites saying that 2 green eyed people can't produce a brown eyed baby? That is what I am getting too. As a few posters have said, genetics can be complicated, and can 'glitch' occasionally.

Like my grandfather had 2 parents who were 5 ft 2 and 5 ft 3. He was 5 ft 3, his one brother was 5 ft 2, and his sister 4 ft 11. His youngest brother was 5 ft 10! Where the F did THAT come from? A previous generation probably!

Sometimes nature, and genetics goes funny! Don't know why you and your DH (both with green eyes,) have produced a brown eyed baby, but you have! 😄

I understood that green is a mutation of brown, in a similar way to hazel. My maternal grandma had green eyes, my grandad had blue, and out of four offspring, two had brown, one had blue, and one had hazel.

That makes sense. My Mam had blue eyes, my Dad Brown. I have hazel eyes as does my children's Dad. My daughter has hazel eyes but they look brown and my son has brown eyes

Eye colour always interests me!

I have blue eyes, 2 blue eyed parents and 3 blue eyed and 1 green eyed grandparent.

My husband has brown eyes , blue eyed and green eyed parents, I’ve no idea what his grandparents had!

Our two daughters both Green eyes! I was hoping they stay blue ..they did until around 2 and both have quite stunning green eyes!

DH and I have brown eyes, DC blue eyes in a quite unusual shade that’s same as my mother’s. My father had hazel eyes, almost green, mine are a kind of browner version

I find eye colour totally mind blowing. We have

Me - green
DH - grey
DS - blue
DD - brown
DD - hazel

🤷🏻‍♀️

I have very brown eyes. DH has blue eyes. We don't actually care what colour eyes our DC have. Interesting hair colour and how curly it is is the big deal in our family.

And yet the first page that I got just says that it's less likely - not impossible.

OP, what are you worried about?

Does this help

But that chart doesn't cover it all, I have brown eyes, DP has blue eyes and ds1 has grey eyes. Almost like they tried to go brown but didn't have enough paint. Like, what happened there?! Ds2 has blue eyes.

That's an interesting chart! Pretty much marries up with the sites that came up for me. A very very VERY small chance of 2 green eyed people producing a brown eyed baby. (The chart said 1%.) Clearly it can happen though, as the OP and her DH have had it happen. As has been said, nature and genetics 'glitch' sometimes!

Agree with PP, eye colour is massively complicated and not what you learned in school.

I have green eyes, my dh blue, all our four children have grey!

😂 made me giggle this reply

According to that chart my husband must be the milkman’s then! His dad had brown eyes, his mum blue eyes and DH has green eyes. According to that chart that’s impossible - but clearly it’s not impossible…

I think genetics are clever than we give them credit for 😁

According to that chart DD can't have green eyes (blue and brown eyed parents) ....but she does.

two brown eyes grandparents.

two blue eyes grandparents.

2 brown eyed parents.
had a child with very blue eyes.

you just never know with eye colour.

Same here!!

Theres loads of genes influencing eye colour.l and scientists have known for a long time that it isn’t simple Mendelian inheritance. It irritates me that it’s taught that way, there are simply inherited diseases that can be used to illustrate the point, we don’t need to use eye colour. In fact, the complexity of eye colour should be taught to illustrate how complicated genetics is as most physical features (and diseases in fact) with a hereditary component are determined much more like this than simple autosomal dominant/recessive patterns.

It's not a glitch. It's just that there are a lot of resources out there that teach the GCSE level eye colour genetics. Which is, as multiple people have pointed out, a ridiculously over-simplified concept. There are far more genes involved in eye colour than we used to think and as are still taught.

It's complicated! I have green eyes, dh has brown. Our kids:
Ds - brown
Dd - green
Ds - blue

I have never met anyone with grey eyes! I thought it was just a fancy way of saying light blue!
