Shoulda paid attention in Health class and biology

So in school, I will openly admit that I was not the sharpest tool in the shed..Baby's eye color has become a big question in my mind lately! My eyes are brown, my hubby's eyes are nearly carolina blue. He has 3 other children(not my biological but his) and 2 of them have blue one has brown eyes. Can anyone suggest. Based on our biology what the chances of eye color will be closer to his then to mine? My mother has brown, my father had changing blues. His Dad blue and his mom dark brown.

Blue is recessive, so if I recall correctly, with you having brown which is dominant, it's only like 25% chance baby has blue eyes

I have looked this up before too! Here is a chart I found.

Edit to add: I'm really hoping our little girl ends up with DH's eyes. They are beautiful hazel and mine are boring brown.

From what I have read it's a 50/50 chance. My husband has brown, I have blue/grey and dd #1 has her daddy's eyes (Yay!). I'm hoping dd #2 has my eyes.

I think there's a 25 percent chance of blue due to it being a recessive gene like PP said. It's based on the Punnett squares from biology. And I think you only have a 25 percent chance if both of you carry the blue eye gene but I could be wrong about that. I have blue eyes and DH a hazel brown but no one in his family has blue eyes. So I'm thinking our children will all have the hazel brown, which I think is beautiful!

If you were to go off the "blue eyes are caused by recessive gene" then your baby would have a 50% chance of having blue eyes. You would be a carrier of the recessive gene since your dad has blue eyes. However, I believe that eye color is caused by the interaction of multiple genes so it won't directly follow that rule.

I have grey-blue and my hubby has pretty hazel brown. Above posters are right about the chances - it's really up in the air right around 50/50! My DH's son (not mine biologically) has his eyes, and his everything else lol. He's like a tiny clone of DH. My daughter's eyes are actually a combo of my ex and me (he has green, I have blue/grey, and hers are blue with some hints of grey AND green near the pupil - her eyes are super pretty).

Fun Fact: There are some cases where the genes can't "make up their mind" and children end up with a combination of blue AND brown. My little brother was born with one blue eye and with one eye that is half blue, half brown, split right down the middle. I have a friend who has blue eyes except for a speck of brown, and another friend who has one bright blue eye and one dark brown eye. Genes are crazy things!

Just to add experience:

Maternal Grandmother - Brown
Maternal Grandfather - Blue
Mother - Brown

Paternal Grandmother - Hazel (I think)
Paternal Grandfather - Blue
Father - Blue

Both our kids had dark brown eyes from day 1. They never even had a chance of changing color, they were just really really dark.

Oh I love these questions! Bringing back the punnet squares! Since your dad has blue and your mom has brown that would make you heterozygous dominant for brown. (Bb) and your husband has homozygous recessive for blue (bb). Which means it would be a 50 percent chance technically. Buuuut lots of research has been done that there are some variations on eye color which factors in your hazel, green, etc... So it is not 100 percent set in stone. Hope this helps

I just want to add 2 things...1. I loved learning about that in school! & 2. The pediatrician we use says baby's eye color can change up until around 18 months.

Yes! That's what I was talking about. Except my percentages were off.

Yes for #2! One of my favorite pictures of my dd was taken when she still had blue eyes. It's crazy to see that picture and look at her now because of how different her eyes look.

So, fun fact. I took a genetics test online one time (on some hospital website) to see what color eyes our little girl would have. It said Brown, since my husband's are brown or hazel. But then it also said it is genetically impossible for me to have blue eyes....yet...here I am. Here is my family history

Maternal:
Mom: Blue eyes, blonde/strawberry blonde hair (Scottish/Irish)
Dad: Brown eyes, black hair (part Cherokee)
Me: Blue eyes, blonde hair

Fraternal:
Mom: Brown eyes, brown hair
Dad: Brown eyes, brown hair
My Hubby: Brown eyes, Hazel eyes

So, who knows. But, I am secretly hoping for a Blonde haired, Blue eyed little girl. Mainly because I love having blonde leg hair....

Yes to the PP who said that eye color changes up to 18 months. DS's eyes were a gorgeous deep blue until he was over a year old. We were so hoping they'd stay but now he has brown eyes like DH. Mine are hazel but BOTH of our fathers have blue eyes so we know the recessive gene is in there somewhere from both sides.

searchingforameaning · May 2016

I have a feeling I have a 0% chance for a blue eyed child. I have blue eyes and so do my parents/siblings.... but DH is from Africa and his family/tribe has brown eyes probably as far back as Adam and Eve... so in your charts, would he not be a BB instead of a Bb? as since I am a bb... all our children are bound to have Bb as a result??? but perhaps a blue eyed grandchild in my future???

cm716 · May 2016

I am blue eyed, I have two blue-eyed siblings,my parents have blue eyes, and all four of my grandparents have blue eyes. My husband's eyes are light green but he has five blue-eyed siblings. Dd1s eyes were blue until she was THREE but have now turned light green.

Don't count your chickens before they are hatched. I thought there was no way that we have anything but blue eyed kids!! I even used to tease my husband that he was going to be out of our blue-eyed Club. Dd2 has very blue eyes but she's only two so we'll see...eye color def changes in kids/toddlers.

Duffgurl · May 2016

I have brown eyes and DH has green eyes but they change to blue too. Our DS1 has a brown eye but it's not just a brown but a lighter color brown. DS2 are more of a Hazel they change from a blue to green to just like what's going on with your eyes lol. I love brown eyes and every other color.

More than likely your DH is homozygous dominant BB for brown. If so you are correct, all of your children would be Bb, But you never know! he may have a recessive b in there.

It depends if YOU have two dominant brown genes or one dominant and one recessive. Your DH had two recessive in order to have blue, so he'll pass on one recessive no matter what. If you have two dominant then the baby will have brown eyes no matter what because baby will have one dominant and one recessive and obviously that brown dominant will take over. However, if you have a dominant and a recessive, then baby has a shot to get your recessive and then the recessive from your DH.

If you are referring to the OP, She doesn't have two dominant BB. Her dad has blue and her mom brown. The only genotype she could be from that pairing is Bb. Even if her mom was BB, she still has to get one genotype from her father. Thus making her Bb.

It is so interesting for me to see how genetics plays out with my kids. I am fair with light blue eyes and my husband is darker with hazel eyes. Our kids are coming out differently each time. My daughter has crystal blue eyes, but our younger son's eyes look like they couldn't decide. The outside of his eyes look blue, but the inside had hazel. In most lights his eyes look green, but in really bright light you can see the difference between the blue and hazel.
