To wonder why DS has brown eyes

[Dinobab]

If DP has hazel (green with brkwn in the middle and bits of blueish colour) and I have light green? How'd that happen?/ I thought brown was dominant so if we had brown genes we would have brown eyes?

[fredfredgeorgejnrsnr]

Eye colour is not a result of a single gene.

en.wikipedia.org/wiki/Eye_color

[Dontneedausername]

You both have recessive brown genes? Also how old is DS? Babies eyes can change colour.

[Dinobab]

Hes 2,my whole family have blue and green eyes, not sure about dps though.. I know his mum has blue

[RokensWife]

We both have brown eyes, our son has blue

[TPel]

Genetics is much more complex than just parents suppling genetic traits.

[harryhausen]

My whole family, DM, DF, DSIS have blue eyes. Mine are brown.

My dh has blue eyes, my dd has blue and ds has brown. I really think eye colour can throw up some complicated gene stuff

[BlinkAndMiss]

My DC both have blue eyes, me and DH both have brown eyes. Loads of people have told us it's not possible but it obviously is.

[BestZebbie]

Eye colour in humans is extremely complicated - much more than GCSE science tries to pretend!
In a simplistic way, brown is the default colour for eyes, and then you get all the other colours by breaking the ability to produce brown in different ways - which is why it is 'dominant' over others, in that if one of your genes is very broken (blue eyes) and the other is totally fine (brown eyes) then you might still produce enough pigment because of the unmutated gene to look brown rather than blue.
Both hazel and green eyes are 'partially broken' but still retain an ability to make darker pigments - either because of two genes mutated in different ways or one gene being 'cancelled out' to some extent by the other as above. If you both pass on the most pigment-producing gene you have to your offspring, it is quite reasonable that they end up with fully brown eyes.

My parents both have blue eyes, I have brown. DSisters both have green. Meh.

[grumpysquash]

Even though brown is generally a dominant genetic trait, it does not have 100% penetrance (meaning that you don't always see it). Also there are colour 'modulating' genes - for want of a better word. It is unusual for brown eyed people to have neither parent with brown eyes, but by no means impossible.

I come from an all Indian family - my dad has blue eyes, my cousin has golden blond hair and hazely brown eyes. Grrr

[FeelsLikeHome123]

YABU. Our dc have the genetic traits of their dgps extended family. Genetics aren't always straight forward. My dc look polar opposites and I have had people ask if they have different dads (they don't) and suggest that Dh may not be their Dad

[bruffin]

I have deep brown eyes as does my DS but my DD has central heterochromia with brown inners and blue/grey outers and a dark ring.
DH has blue grey eyes but my mum had hazel eyes and dad typical greek colouring. My nieces have mixed eyes as well, mum dark brown eyes and dad has blue eyes

[ChatEnOeuf]

Eye colour genetics is fascinating but not at all simple. DD has beautiful big brown eyes...DH is hazel, I'm green. Definitely no paternity issues

[PeasinPod1]

I have brown eyes and olive skin/black hair. DH is paler but grey/brown eyes/brown hair. Yet we have a completely scandi looking DS, fair blond hair and blue eyes! Was a huge shock!

[Sighing]

Hazel eyes include brown in the iris (as well as green and/or blue). So he gets the brown from both of you.

[whooshbangprettycolours]

My daughter has dark brown eyes, no one in either family has brown! I can guarantee she's mine and my DH. Apart from the eyes she is the spitting image of my DH.

[AskingForAPal]

That's fascinating, thanks for explaining BestZebbie

[AngelBlue12]

I have bright blue eyes and DH has light brown eyes we have:

DD1 dark brown
DD2 light blue
DD3 green
DD4 bright blue
DD5 bright blue

[MarmiteAndButter]

Green is a subset of brown. Simples.

[SoupDragon]

Actually it's anything but "simples" :)

[Blodss]

My Father has brown eyes, my Mother light green and I have dark green with brown in. Husband has blue eyes and both our children have blue.

[Phoenix0x0]

I have very very dark brown eyes, as does my DF.

My mum has mid brown eyes.

My sister has blue eyes!

My paternal GM had green eyes and my maternal GF had blue, so this accounts for my sisters blue eyes.

[shouldwestayorshouldwego]

It could just be our family but the colour fades over time. I always had really dark brown eyes, 'your father's eyes' except his weren't quite as dark as mine. Fastforward x years and his eyes are a v light brown hazel colour, mine are still brown but not the dark nearly black colour that they were. My dc have the eyes that I used to have! I guess that in the same way that hair loses the melatonin and goes grey/ white, the cells in our eyes have stopped making as much melatonin.
