Blue Eyes - Green/Brown Parents

[mmmmchocolate]

Hi, can anyone help me. My 5 month old DD has really lovely blue eyes, myself i have brown eyes and DF has green eyes.

I am forever getting people coming up to me and saying 'where ever does she get those blue eyes from'. Has anyone else had this or can advise me if they will change or if they should change!!??!?!

Thank you

my 2nd babbas eyes changed colour at 12 months, well gradually until about 3

My dad has blue eyes, my mum has brown ... my mum was sure that at least one of her children would have brown eyes .... but no ... DB1 hazel eyes (I guess that is a sort of brown) DSis has green eyes, DB2 has sky blue eyes and I have green/grey/blue eyes depending on my mood and the weather!!!!
DH has brown eyes .... DS has the bluest eyes I have every seen and DD has dark sludgy, greeny, browny, muddy pooly colour eyes ...
None of it makes sense to me ....

Yup or AB

the reason why O is an universal donor is because A and B blood type have respectively A and B antigens on their blood cells.

if you give B blood to and A blood patient anti-B antibodies will recognize it as alien and attack it.

O blood type do not have those antigens. their blood normally will not be rejected when it is given to others.

I think it is one of the things that puzzle scientists as to why women don't attack their babies as their cells are essentially aliens to ours

No one matches in our house!
i have green eyes
dh has blue/grey eyes
ds has green/blue eyes (okay he and i match!)
dd1 has brown eyes
dd2 has blue eyes.....
so none of my children have the same colour eyes as each other! this is quite noticable in photos...
we will be taking bets on any next babys.......!

think I remember that green in all its shades (like hazel, green-brown, etc) is the easiest colour to happen for eyes genetically (sorry, can't explain it better!). I mean, a lot of possible combinations would lead to it and it's harder to trace.
My ds had a lovely metalic-gray shade of eyes till he was about 18 months (I was told their eyes can change up to 8 months but clearly not true) - and after that they changed to some hazel-green-brown colour.

me and dh v brown - hair and eyes - ds v blue and blonde. Just like me and my dad - his eyes changed around age of 4 (late developers in our family) and my hair changed around age of 7 - anyone else come across eyes changing so late ?

My kids all had beautiful blue eyes when they were little - they probably started changing around age 7 - now they all have specks of different colours in, including yellow if you look closely! The apparent colour (if you don't look closely) ranges from pretty much grey, to grey-blue, through green-blue to almost green.

I too was taught that 2 x blue eyed parents couldn't have a brown eyed child - thanks tamum and mimsie for re-educating me.

Thanks for link to website - really interesting and i am looking forward to querying this in my lectures . So I better let my mum know that her sister wasnt naughty at all!!

Ooh, sorry, I missed some of this. Mimsie's link is great, there's another here that is written by one of the most eminent human geneticists alive (unusually, he has written it in the first person!). I can give you lots of references to primary research papers Awen, but I think it's unlikely your tutor will thank you- they're all heavy going SNP mapping statistical stuff

tamum, I always teach the very basic and wrong single gene crap, because they have to be able to 'do' a punnet square for their GCSE. And then I tell them....'it is all much more complicated than this and more than one gene is involved, as it is with skin colour'.

Just been teaching this, in fact..

That sounds good- I know you have to be able to come up with sensible examples for punnet squares and so on. Most books don't have any disclaimers though, which I think is a bit misleading.

Ds1 had blue eyes till he was about 3, when they changed to a greeny grey colour. I was suprised they changed so late.
