Anyone else fine Eye colour genetics fascinating?

[ThanksForAllTheFish]

Just randomly thinking about eye colours and the genetics behind them tonight. (I find genetics fascinating). What eye colour do you, your partner and children have? Anyone have rare occurrences ie: two brown eye parents having blue eyes child or 2 different coloured eyes etc.

I have blue eyes, DH has green eyes that occasionally look a bit orange/light brown depending on lighting. DD has Grey eyes - they look blueish most of the time, grey when she wears dark clothes or at night and greenish in photos. Out of all our eye colours I like DD’s the best as they look particularly striking when they are ‘grey’.

@ILoveYou3000

As you would imagine most green eyes are concentrated in caucasian communities so there will be a higher proportion here then say Africa or Asia.

Have you ever seen someone with both very dark skin and blue eyes? It's very striking. Or pink eyes (albinism)?

My parents are both blue eyed, and so are me and my brother. MIL has amazing pale green eyes, FIL has blue eyes, SILs both have hazel eyes, DH has blue eyes (we have almost exactly the same colour blue with flecks of green and grey weirdly). DS has bright blue eyes.

mine are pretty much like this, which actually looks a bit weird but I don't think it's that noticeable

My mum & Dad both had blue
DH parents mil blue & DIL grey/blue/green/hazel mix

I have blue eyes
Husband has dark brown eyes

Both our girls striking green colour! They stayed blue until around 2 years of age

I, dh, ds and dd have blue eyes. But different shades of blue.

Me: hazel
Dh: brown
Dd1: brown
Dd2: blue (only living person I’m related to with blue)
Ds1: brown

I know blue eyes are a recessive gene and my husband will carry the gene from his mum, but on my side the closest person to me with blue eyes is my great-grandad!

My Dad has quite pale blue eyes and my Mum’s are greyish blue. One of my brothers has the most startling bright blue eyes I have ever seen. He gets a very creepy Rasputin-like stare when he’s a bit pissed too. It’s quite odd. Some years ago we found a very old picture of a great great grandfather which, while black and white so not certain, looks to have exactly the same bright staring eyes. Genetics are awesome!

My DD’s eye colour is as if someone mixed my dark brown and her father’s grey with golden bits - i.e. like genetics apparently is not supposed to work
she has hazel eyes with gold bits 🤷🏼‍♀️

I have two dds, one has brown eyes one blue.

They have 2 brown eyed parents and only one blue eyed grandparent. The force was strong in that one blue eyed gene!

Me - greeny blue
Exh - greeny brown (hazel)
DS - brown!

My parents both have blue eyes. I have brown. My biology teacher was adamant it was impossible and I was lying.

DH has grey.
DD1 has brown.
DD2 was born with a full head of black hair and blue eyes. Her eyes went brown within a few months. Her hair went to white blonde, then to brown, and has now settled on dark blonde.

I totally love eye colour

Mum - green
Dad - brown
Older sister - brown
Middle sister - bright blue
Me - green
DH - grey
DS - my sister's bright blue ( guessing it must have been a recessive gene compared to a green one I inherited)

So I worked out
Dad - has a brown(dominant) and blue
Mum has green,(dominant) and blue

I’m half Asian and have dark blue eyes. My father who is half Indian has blue eyes and my mother who is Malaysian of Portuguese descent has brown eyes.

My children’s father who is Hungarian has brown eyes and my son has brown eyes and my daughter has the same colour eyes as me.

When my daughter was born her father was under the false impression that his brown eye gene was dominant over my blue eye gene and he made a very nasty comment about our daughter not being his when she was born because of her eye colour.

Sorry, if this has been answered already (I haven’t read all the comments).

Both DH and I have very dark brown eyes but BOTH of our children have blue eyes.

Both sets of grandparents have brown eyes too. My great grandmother had blue eyes.

Can someone explain in really simple terms how the genes would have worked?

I assume both DH and I must have the recessive blue eye gene for blue eyes to appear in our children?

Getting a bit sick of the milkman jokes....

I know the feeling @mypatronus

I think the way genetics is taught to most of us is extremely rudimentary which can cause people to feel unnecessarily embarassed/apologetic/baffled when their child turns out not to be a mini-me of either parent genetics wise.

My poor dd had to sit in her german class and listen to everyone else saying (in german) "my dad has blonde hair and blue eyes, my mum has brown hair and brown eyes. I have brown hair and blue eyes"

When it got to her turn she had to explain that whilst her whole nuclear family basically had brown hair and brown/hazel eyes she had red hair and blue eyes". Milkman/adoption jokes abounded. It's just irresponsible.

Yep blue genes are recessive so you have to have 2 blue genes to get blue. Brown dominates everything so just one brown gene in a family can mean all people have brown eyes.

My mum and dad both have blue eyes
My twin sister and I have green eyes (as did our great grandma)
My dh has blue eyes
Our dd has bright blue eyes

On dh's side there are a parents who both have blue eyes who have one blue eyed, one brown eyed child.

The brown eyed child looks like her father, so there's no question of parentage, but on basic genetics that shouldn't happen.
Kind big brother told her she's a mutant.

Basic genetics are:
Everyone has 2 genes for eye colour. Either Bl (Blue) or Br (Brown)
Brown is dominant, so if you have one or two Brown genes you will have brown.
So of the four combinations three come out with brown:
Br Bl; Bl Br; Br Br

The only way to get Blue eyes is to have Bl Bl.

So if you have 2 blue eyed parents they can only have Blue eyed children.

But with brown eyes it's different. Each parent gives one of their genes to the child.
So if you have 2 brown eyed parents who both are Br Bl
Then the possible combinations for a child are:
Br Br; Br Bl; Bl Br; Bl Bl
So approximately 1 in 4 of their children will have Bl Bl ie blue eyes.

If one parent is Br Br, it doesn't matter what the other parent has, the children will all be brown as they will inherit at least on Br gene.

That's very basic, and the real terms is much more complicated. But it is fascinating. Green eyes are a mutation so not really included here.

My dad had blue eyes, my mum had brown eyes (hers are now 1 green, 1 blue), my sister has hazel eyes, brother has blue eyes, brother has brown eyes, I had brown eyes they are now green.

My husband has blue eyes with a star pattern on the iris. My daughter has darker blue eyes than her dad but with the same star pattern. My son has multicoloured eyes - they are brown next to the pupil, then a wide green ring, then a narrower blue ring on the outside. It's very distinct! And quite unusual I'm told. They might change as he ages, given my mother and I both changed eye colour.

I had a friend whose parents were Pakistani, her siblings were all undeniably Pakistani, but she was white as porcelain, freckles, and very red hair. Her grandmother was Irish and she was her grandmother's spitting image, but she looked so different to all her immediate family it really upset her.

My daughter is half Far East Asian but has green eyes ringed in grey, how mine used to look when I was young (mine have faded now to a more washed out hazel).

DH has green eyes, mine are hazel. My mum has green eyes, my dad's are bluish.
My dd1 has blue eyes with yellow around the pupil. Dd2 eye colour is really hard to describe. Maybe closest to green but not really green.

I knew a couple whose three children were all startlingly different

Olive skinned with brown and brown
Pale and freckly with red and pale blue
Medium white with blonde and green

My parents are both brown eyed as is my sister
I’m blue eyed 🤷🏻‍♀️
. Dh is blue eyed too and dd brown. She’s not mine biologically and found it upsetting that she was different to us, until I pointed out how I am completely different to my full bio family

My sister was actually born with brown eyes which is fairly uncommon. Handy though as when mum was given the wrong baby in the hospital (1967) to feed her that night, she realised and insisted on getting her actual baby ... imagine!
My sister was being breast fed by some oblivious woman.

DH green eyes
Me dark brown eyes
Ds1 Blue eyes
Ds2 light brown eyes almost a gold colour
Ds3 dark brown eyes
Ds4 blue eyes
Dd green eyes

DH and I both have brown eyes and brown hair. Every single member of our families have brown hair and eyes, except my eldest nephew who has brown eyes and ginger hair. We don’t know where it’s came from in either of them but I the family has decided it’s a throwback to the same distant relative.
