What colour eyes and hair is your baby likely to have?

[Louise N]

The baby's eye colour will actually be defined by the grandparents eye colours - as you'll carry 2 genes, one from your mother and father and same for baby's father. Your eye colour will of course be your most dominant gene but it could go either way.

For me, I have blue eyes. I have 1 parent with blue eyes and 1 with green.
Hubby has brown eyes. He has 1 parent with brown eyes and the other green.

Chances are that our baby has a 2 in 4 chance of green eyes and 1 in 4 of blue or brown - even tho' me and hubby have blue and brown eyes, baby has more chance of green

Yes, this is right. Eye colour is determined by your genes, not what YOUR eye colour is, ie, of course you get your eye colour from your genetic make-up, but you carry two genes and together with your partner, 2 of yours and his 4 eye colour genes, will come together to make the eye colour of your baby, and the dominant gene of the 2 should be the colour eyes your baby gets. That's not explained how it is in my head, and it's so much easier when teaching kids about it!

Eye colour, hair colour, skin pigmentation and yada yada yada can ONLY be determined by genetics... by the chromosones we get from each parent. If you went down your entire ancestry to the year dot and knew everything about their genetic makeup, you'd have an exact knowledge of the probability of certain coloured eyes. My husband has brown/brown and I have brown/blue so Our baby has a more or less 3 in 4 chance of brown eyes.

So its not just grandparents that determine the eye colour, it is the parents too. I said in a few posts back that i read that you carry 2 types of gene colour per person so im glad thats correct.

Thanks Carrie, i'm glad someone else knows what i'm trying to describe!

but Rozie, where does your geneotype come from - Your Parents.
Where does your OH's genotype come from - His Parents.
I.E The baby's Grandparents! Your eye colour has nothing to do with it, it's the genes you carry from your parents. Likewise your eye colour would have been determined by your grandparents.

Ohh man

Sorry Emx, completely hijacked your thread today!

If you are trying to indicate that im thick then stop right there. All i was trying to say is, that me and my OH's eye colour will contribute to what eye colour baby has because of the 2 genes we carry from OUR PARENTS as you kindly pointed out!!! You really have a way with words don't give up the day job huh!

Ask a Geneticist

by Dr. Barry Starr, Stanford University


Is it possible for two brown eyed people to have a child with blue eyes? Both of these people have one parent with blue eyes,and one parent with brown eyes.

Can brown-eyed parents have a blue-eyed baby?


-An undergraduate from Tennessee and a curious adult from Ohio

March 13, 2004

The short answer is that brown-eyed parents can have kids with brown, blue or virtually any other color eyes. Eye color is very complicated and involves many genes. To begin to understand how parents with brown eyes could have blue-eyed children, let's imagine that eye color is due to a single gene, EYCL3, which comes in two versions or alleles, brown (B) and blue (b).




Example of one
gene modelRemember that for most genes (including eye color), you have two copies of each gene that you inherited from your mother and your father. The brown version of the eye color gene (B) is dominant over the blue version (b). Dominant means that if either of your genes is the B version, then you will have brown eyes. Genetically speaking, then, people with brown eyes could be either BB or Bb while people with blue eyes could only be bb.

For two parents with brown eyes to have a blue-eyed child, both parents must genetically be Bb. When this happens, there is a 1 in 4 chance that these parents will have a bb child with blue eyes.

Unfortunately, eye color is not as simple as this. Besides the EYCL3 gene described above, at least two other genes, EYCL1 and EYCL2, are also involved. Although this set of genes explains how people can have green eyes, it does a poor job of explaining how blue-eyed parents could have brown-eyed children or how anyone can have hazel or gray eyes at all.

To understand green eyes in all of this, we only need to review EYCL1 and EYCL3. (EYCL2 is a poorly understood central brown eye color gene.)


The two gene model
for eye color
Remember, EYCL3 has two versions, brown (B) and blue (b). EYCL1 also comes in two versions, green (G) and blue (b). The way these genes work is that if you have a B allele, you will have brown eyes (B is dominant over b and G), if you have a G allele and no B allele, you will have green eyes (G is dominant over b) and if you have all b genes, then you will have blue eyes. Two possibilities are shown below:

I hope this helps to answer your question. As you can tell, while some progress has been made, eye color is a very complex, polygenic trait that is not yet fully understood.

Ha ha - thats ok!! It is obviously a very interesting topic - I havent looked further into the eye colour debate as blue is a given - have ginger on both sides though so am thinking redhead may be likely too!!

 

[honeygrl]

Don't get set on blue eyes.. both my parents have clear bright blue eyes but mine ended up hazel... i'm the only person in my whole family with hazel eyes.

 

[mumof42be]

mine will no doubt be blue eyes and brown hair....my other 3 kids were born like with them

For some reason none of this stuff tells anything about hazel eyes. My DH and I both have hazel eyes but they are very different versions of hazel. Mine are blue with yellow inside and his are brown edged with green inside... guess there's no telling what our kid will end up with!

Also, according to the calculator my mom must have cheated on my dad to have me... haha It says 2 people with blue eyes can only have a kid with blue eyes. Didn't work that way in my case because both my parents have bright blue eyes and I don't.

 

[honey08]

2blue eyes people cant have anyother colour my mams mam and dad have blue eyes, me mam does her sister but her bro has brown eyes she had an affair !!
both me and OH have blue OH has brown hair mines fairly red but morgans got brown hair

Yes, this basically is for blue eyes, green eyes, and brown eyes.....they fully do not understand (grey, or hazel eyes)..... eye color is a 'polygenetic trait' that is not fully understood..... They did say however, "Eye color comes from a combination of two black and yellow pigments called melanin in the iris of your eye. If you have no melanin in the front part of your iris, you have blue eyes. An increasing proportion of the yellow melanin, in combination with the black melanin, results in shades of colors between brown and blue, including green and hazel."


I found a link for 2 blue eyed parents with a brown eyed child which he explains can happen by a mutation or an enviornmental influence...

My hubby and I both have light brown hair and I have greenish blue eyes and he has blue eyes so I'm guessing light brown hair and blue eyes, though will probably have blond hair as a child as we both did ..

 

[Shelby2007]

Traits are much more deeper than just the parents sweetie! So please dont get your hopes up if you child doesnt have blue eyes!!!

 

[MiissDior]

Other Half has Black Hair & Greeny eyes
I have Black hair (natural VERY dark brown) & Blue eyes

i had bleach blonde hair when having my daughter && she was born with
jet black hair and i never got to see her eye colour she was born sleeping

think this wee man will have dark hair too

 

[Nic1107]

The calculator thing told me I'm lying. My parents both have blue eyes; my dad's dad had brown eyes, my mom's dad has blue eyes, and both of my grandmothers have green eyes. I got my grandmothers' green eyes, but it says that since both of my parents are blue, that couldn't be! My eyes couldn't possibly be greener, and there is no question of my paternity! grrrr

Anyway, DH has dark brown eyes, as does his entire family, so it's likely our kids will too. I would love if at least one has my green eyes though, and it would be interesting if any got my parents' blue eyes. As for hair colour, DH's is black and mine is light brown, so my guess is the kids will have medium-to-dark brown hair.

 

[toseland13]

i have green eyes which are sometimes yellow lol i know its strange, and i have brown/blonde hair, my hubby has dark hair and grey eyes. havent got a clue what baby will have. when we were both born we had black hair then it went blonde then when older went darker but he is back to black and im brown/blonde so who knows

 

[graciebaby]

Me-Dark blue eyes
Partner-brown eyes

Me- Mousey Brown hair, altho blonde when little
Partner-Pure white blonde when little, now mousey colour. Red does run in his family tho. His gran was red when younger and he has uncles and aunties that are red too.

My little girl has Blue eyes, and blonde hair. Not white tho.

My mum has brown eyes and my dad has blue eyes, so i got the blue eyes from him.
My partners mum and dad both have brown eyes.

Not sure what eye colour or hair colour our new baby will have. My eyes are really dark blue so i'm thinking blue eyes again.

Before I start my spelling is really bad, I have a degree in Zoology not english so sorry for all the mistakes!

It depends on the recessive colours too, you each pass down 2 chromosomes that will colour your babies hair and eyes, if you pass your reccessive colour (which might be the colour of your great great grandmother) and your husband does too then it will be that colour, hense in the dominican republic, 2 black parents with brown eyes and black thick hair can have a blue eyed blonde child because centurys ago the spanish collanised the island. Although generally as a rule, dark colours like brown are stronger than blue, you do still require the same colour from each parent. My niece has hazel/green eyes and both her parents have the darkest bown eyes you've ever seen.

I hope mine have my coloured hair mid/dark brown with hubbies beautiful blue/grey eyes if its a boy and if its a girl his hair light/blonde brown with my brown eyes - whatever colours it has I really hope it is more like daddy, slim and athletic rather than more short and stocky!!!

[honey08]

also can i just say that wotever hair colour u have u or OH doesnt mean the baby will have the same,red hair comes out in genarations ,u wil just have to see wot ur suprise will be, my LO got brown hair, mines fairly red, OH is brown ,BUT my bro and his gf both have brown hair and there LO has gone red !! u wud think my babies his and his is mine !! xxxxx

 

[Vicyi]

My mum had strawberry blonde hair and green eyes when she was little (she now has medium brown hair)
My dad had white blonde hair and brown eyes when he was little (he has pretty much black hair now) and they had 4 children -
My sister has brown hair, brown eyes (still does)
I had brown hair, hazel eyes (still do)
My sister had white blonde hair and brown eyes (she now has dark brown hair)
My brother had yellow blonde hair and grey eyes (he now has dark brown hair and green/grey eyes)

I have dark brown hair and hazel eyes (more brown) and my OH has dark brown hair and hazel eyes (more green) - our daughter has light brown hair and hazel eyes (more green) so im guessing out next bubba will be the same but we seem to have all colours in our family so could go any way!!
